completed implementation of exceptions in `SocialVoid.Errors` namespace

----------------------------------------------------------------------- 1. Added `AuthenticationErrors`, `MediaErrors`, `NetworkErrors`, `ServerErrors` and `ValidationErrors` namespaces. 2. Added `Tests.Errors` namespace (using `NUnit.Framework` as test framework), 3. Added github workflows for testing the library, 4. Added `dependabot` and `stale` configurations to the project. 5. Added `CODESTYLE.md` file. Signed-off-by: Aliwoto <aminnimaj@gmail.com>

+name: Bug fix
+about: Create a bug fix to help us improve the library
+---
+
+Note: New issues raised, where it is clear the submitter has not read the issue template, are likely to be closed with "please read the issue template". Please don't take offense at this. It is simply a time management decision. If someone raises an issue, and can't be bothered to spend the time to read the issue template, then the project maintainers should not be expected to spend the time to read the submitted issue. Often too much time is spent going back and forth in issue comments asking for information that is outlined in the issue template.
+
+
+#### Preamble
+
+General questions may be better placed [StackOveflow](https://stackoverflow.com/).
+
+Where relevant, ensure you are using the current stable versions on your development stack. For example:
+
+ * Visual Studio
+ * [.NET SDK or .NET Core SDK](https://www.microsoft.com/net/download)
+ * Any related NuGet packages
+
+Any code or stack traces must be properly formatted with [GitHub markdown](https://guides.github.com/features/mastering-markdown/).
+
+
+#### Describe the bug
+
+A clear and concise description of what the bug is. Include any relevant version information.
+
+A clear and concise description of what you expected to happen.
+
+Add any other context about the problem here.
+
+
+#### Minimal Repro
+
+Ensure you have replicated the bug in a minimal solution with the fewest moving parts. Often this will help point to the true cause of the problem. Upload this repro as part of the issue, preferably a public GitHub repository or a downloadable zip. The repro will allow the maintainers of this project to smoke test the any fix.
+
+#### Submit a PR that fixes the bug
+
+Submit a [Pull Request (PR)](https://help.github.com/articles/about-pull-requests/) that fixes the bug. Include in this PR a test that verifies the fix. If you were not able to fix the bug, a PR that illustrates your partial progress will suffice.

+
+> #### NOTE: This code style standard for SocialVoid.NET is a work in progress and much of the code does not currently conform to these rules.  This is something that will be addressed by the core team.
+
+# Introduction
+As the SocialVoid.NET project gains more traction and becomes more widely used, we aim to provide a more professional and consistent look to the large amount of source now in the project.  It was a broadly supported decision by the core development team to follow the Microsoft coding guidelines (the default provided in Visual Studio's C# editor).  These coding guidelines listed below are based on a [MSDN blog post](http://blogs.msdn.com/b/brada/archive/2005/01/26/361363.aspx) from 2005 by Brad Abrams describing the internal coding guidelines at Microsoft, with some changes to suit our project.
+# Coding Guidelines
+
+## Tabs & Indenting
+Tab characters (`\0x09`) **should** be used in code. All indentation should be done with Tab Size of 4.
+
+<hr/>
+
+## Bracing
+Open braces should always be at the beginning of the line after the statement that begins the block. Contents of the brace should be indented by 4 spaces. Single statements **should** have braces. For example:
+```csharp
+if (someExpression)
+{
+	DoSomething();
+	DoAnotherThing();
+}
+else
+{
+	DoSomethingElse();
+}
+```
+
+`case` statements should be indented from the switch statement like this:
+```csharp
+switch (someExpression) 
+{
+	case 0:
+		DoSomething();
+		break;
+	case 1:
+		DoSomethingElse();
+		break;
+	case 2: 
+	{
+		int n = 1;
+		DoAnotherThing(n);
+	}
+	break;
+	case 3:
+	{
+		DoSomething();
+		break;
+	}
+}
+```
+
+Braces also **should** be used for single statement blocks immediately following a `for`, `foreach`, `if`, `do`, etc. The single statement block should always be on the following line and indented by Tab. This increases code readability and maintainability.
+```csharp
+for (int i = 0; i < 100; ++i)
+{
+	DoSomething(i);
+}
+```
+
+<hr/>
+
+## Single line property statements
+Single line property statements can have braces that begin and end on the same line. This should only be used for simple property statements.  Add a single space before and after the braces.
+```csharp
+public class Foo
+{
+	int bar1;
+
+	public int Bar1
+	{
+		get { return bar1; }
+		set { bar1 = value; }
+	}
+
+	public int Bar2 { get; set; }
+}
+```
+
+<hr/>
+
+## Commenting
+Comments **should** be used to describe intention, algorithmic overview, and/or logical flow.  It would be ideal if, from reading the comments alone, someone other than the author could understand a function's intended behavior and general operation. 
+
+While there are no minimum comment requirements (and certainly some very small routines need no commenting at all), it is best that most routines have comments reflecting the programmer's intent and approach.
+
+Comments must provide added value or explanation to the code. Simply describing the code is not helpful or useful.
+```csharp
+	// Wrong
+	// Set count to 1
+	count = 1;
+
+	// Right
+	// Set the initial reference count so it isn't cleaned up next frame
+	count = 1;
+```
+
+<hr/>
+
+### Copyright/License notice
+Each file **should** start with a copyright notice. This is a short statement declaring the project name and copyright notice, and directing the reader to the license document elsewhere in the project. To avoid errors in doc comment builds, avoid using triple-slash doc comments.
+```csharp
+/*
+ * This file is part of SocialVoid.NET Project (https://github.com/Intellivoid/SocialVoid.NET).
+ * Copyright (c) 2021 SocialVoid.NET Authors.
+ *
+ * This library is free software: you can redistribute it and/or modify
+ * it under the terms of the GNU General Public License as published by
+ * the Free Software Foundation, version 3.
+ *
+ * This library is distributed in the hope that it will be useful, but
+ * WITHOUT ANY WARRANTY; without even the implied warranty of
+ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ * General Public License for more details.
+ *
+ * You should have received a copy of the GNU General Public License
+ * along with this source code of library. 
+ * If not, see <http://www.gnu.org/licenses/>.
+ */
+
+```
+
+<hr/>
+
+### Documentation Comments
+All methods should use XML doc comments. For internal dev comments, the `<!-- -->` tag should be used (you can also use <devdoc>).
+> after your pull request is accepted by the moderators, we will add `<code> Since: v0.0.0 </code>` to the XML comments so the users won't be confused about version conflicts.
+
+```csharp
+/// <summary>
+/// The Foo class has usage of ....
+/// <code> Since: v0.0.0 </code>
+/// <summary>
+public class Foo 
+{
+	/// <summary>
+	/// Public stuff about the method
+	/// <code> Since: v0.0.0 </code>
+	/// </summary>
+	/// <param name="bar">
+	/// What a neat parameter!
+	/// </param>
+	/// <devdoc>
+	/// Cool internal stuff!
+	/// </devdoc>
+	public void MyMethod(int bar)
+	{
+		...
+	}
+}
+```
+
+<hr/>
+
+### Comment Style
+The `//` (two slashes) style of comment tags should be used in most situations. Wherever possible, place comments above the code instead of beside it.  Here are some examples:
+
+```csharp
+	// This is required for WebClient to work through the proxy
+	GlobalProxySelection.Select = new WebProxy("http://itgproxy");
+
+	// Create object to access Internet resources
+	WebClient myClient = new WebClient();
+```
+
+<hr/>
+
+## Spacing
+Spaces improve readability by decreasing code density. Here are some guidelines for the use of space characters within code:
+
+**Do** use a single space after a comma between function arguments.
+```csharp
+Console.In.Read(myChar, 0, 1);		// Right
+Console.In.Read(myChar,0,1);		// Wrong
+```
+
+**Do not** use a space after the parenthesis and function arguments.
+```csharp
+CreateFoo(myChar, 0, 1);			// Right
+CreateFoo( myChar, 0, 1 );			// Wrong
+```
+
+**Do not** use spaces between a function name and parentheses.
+```csharp
+CreateFoo()							// Right
+CreateFoo ()						// Wrong
+```
+
+**Do not** use spaces inside brackets.
+```csharp
+x = dataArray[index];				// Right
+x = dataArray[ index ];				// Wrong
+```
+
+**Do** use a single space before flow control statements.
+```csharp
+while (x == y)						// Right
+while(x==y)							// Wrong
+```
+
+**Do** use a single space before and after binary operators.
+```csharp
+if (x == y)							// Right
+if (x==y)							// Wrong
+```
+
+**Do not** use a space between a unary operator and the operand.
+```csharp
++i;								// Right
++ i;								// Wrong
+```
+
+**Do not** use a space before a semi-colon. 
+**Do** use a space after a semi-colon if there is more on the same line.
+```csharp
+for (int i = 0; i < 100; ++i)		// Right
+for (int i=0 ; i<100 ; ++i)			// Wrong
+```
+
+<hr/>
+
+## Naming
+Follow all .NET Framework Design Guidelines for both internal and external members. Highlights of these include:
+* **Do not** use Hungarian notation
+* **Do** use an underscore prefix for member variables, e.g. "_foo"
+* **Do** use camelCasing for member variables (first word all lowercase, subsequent words initial uppercase)
+* **Do** use camelCasing for parameters
+* **Do** use camelCasing for local variables
+* **Do** use PascalCasing for function, property, event, and class names (all words initial uppercase)
+* **Do** prefix interfaces names with "I"
+* **Do not** prefix enums, classes, or delegates with any letter
+
+The reasons to extend the public rules (no Hungarian, underscore prefix for member variables, etc.) is to produce a consistent source code appearance. 
+In addition, the goal is to have clean, readable source. Code legibility should be a primary goal.
+
+<hr/>
+
+## File Organization
+* Source files should contain only one public type, although multiple internal types are permitted if required.
+* Source files should be given the name of the public type in the file.
+* Directory names should follow the namespace for the class after `SocialVoid`. For example, one would expect to find the public class `SocialVoid.Constants.WotoTools` in **SocialVoid\Constants\WotoTools.cs**.
+* Class members should be grouped logically, and encapsulated into regions:
+
+```csharp
+	//-------------------------------------------------
+	#region Constant's Region
+	// some members here
+	#endregion
+	//-------------------------------------------------
+	#region static Properties Region
+	// some members here
+	#endregion
+	//-------------------------------------------------
+	#region Properties Region
+	// some members here
+	#endregion
+	//-------------------------------------------------
+	#region static field's Region
+	// some members here
+	#endregion
+	//-------------------------------------------------
+	#region field's Region
+	// some members here
+	#endregion
+	//-------------------------------------------------
+	#region static event field's Region
+	// some members here
+	#endregion
+	//-------------------------------------------------
+	#region event field's Region
+	// some members here
+	#endregion
+	//-------------------------------------------------
+	#region Constructor's Region
+	// some members here
+	#endregion
+	//-------------------------------------------------
+	#region Destructor's Region
+	// some members here
+	#endregion
+	//-------------------------------------------------
+```
+
+and as for methods (you have to place the methods after normal members):
+
+```csharp
+	//-------------------------------------------------
+	#region Initialize Method's Region
+	// some methods here
+	#endregion
+	//-------------------------------------------------
+	#region Graphical Method's Region
+	// some methods here
+	#endregion
+	//-------------------------------------------------
+	#region event Method's Region
+	// some methods here
+	#endregion
+	//-------------------------------------------------
+	#region overrided Method's Region
+	// some methods here
+	#endregion
+	//-------------------------------------------------
+	#region ordinary Method's Region
+	// some methods here
+	#endregion
+	//-------------------------------------------------
+	#region Get Method's Region
+	// some methods here
+	#endregion
+	//-------------------------------------------------
+	#region Set Method's Region
+	// some methods here
+	#endregion
+	//-------------------------------------------------
+	#region static Method's Region
+	// some methods here
+	#endregion
+	//-------------------------------------------------
+```
+
+* lines should be used between regions, until the 60th character of that line.
+* Using statements **should** be before the namespace declaration.
+
+```csharp
+using System;
+
+namespace MyNamespace 
+{
+	public class MyClass : IFoo 
+	{
+		//-------------------------------------------------
+		#region Constant's Region
+		public const int constInt = 10;
+		#endregion
+		//-------------------------------------------------
+		#region static Properties Region
+		/// <summary>
+		/// The Big Father of the <see cref="GraphicElement"/>!
+		/// </summary>
+		public static SomeClass AnotherClass
+		{
+			get => ThereIsConstants.AllClasses.AnotherClass;
+		}
+		#endregion
+		//-------------------------------------------------
+		#region Properties Region
+		public virtual WotoRes MyRes { get; set; }
+		#endregion
+		//-------------------------------------------------
+		#region Constructor Region
+		public MyClass()
+		{
+			...
+		}
+		#endregion
+		//-------------------------------------------------
+		#region Destructor's Region
+		~MyClass()
+		{
+			...
+		}
+		#endregion
+		//-------------------------------------------------
+		#region ordinary Methods
+		void DoSomething()
+		{
+			...
+		}
+
+		void FindSomething()
+		{
+			...
+		}
+		#endregion
+		//-------------------------------------------------
+	}
+}
+```

+# Errors
+
+Socialvoid has it's own unique set of error codes aside from the ones
+used by the standard of the RCP server. while your client should handle
+standard error codes of the RCP protcol; if you are building a Socialvoid
+client then it's important that your client can handle and represent these
+errors returned by the Socialvoid Server.
+
+These errors are designed to explain what the issue is to the client or
+user, in cases the client use these errors to automatically correct their
+request but some errors may be caused by users as well. so it's important
+that your client can understand and catch these errors accordingly.
+
+
+## Error Codes
+
+Errors come in three components.
+
+ - Name
+ - Code
+ - Message
+
+### Name
+The name is the name of the error, it can be anything from `PeerNotFound`
+to `InternalServerError`, this makes it easier for programming languages
+to use a try catch statement to catch specific errors.
+
+### Code
+The error code is an alternative way to identify the error when the
+name is not available or trying to catch a wide range of specific errors.
+These are usually represented in integers.
+
+### Message
+A message explains more details about the error, while the same error
+can occur for Situation A and B; Situation B may have a different reason
+for the same error. This should not be used as a way to identify the error
+and usually serves the purpose of troubleshooting or displaying the error
+to the user.
+
+--------------------------------------------------------------------------
+
+## Error Types
+
+Errors are split into sections to make it more easier to manage, you can
+either identify errors indivdually by their error code or by range.
+
+| Section               | Set | Range         | Description                                                                                                                                                                                                |
+|-----------------------|-----|---------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| Validation Errors     | 21  | 8448 - 8703   | Errors that returns when the given parameters or data is invalid in some way or another                                                                                                                    |
+| Authentication Errors | 22  | 8704 - 8979   | Errors related to authentication/session management, these errors are usually returned when there was an error while trying to authenticate or there are session errors such as the session being expired. |
+| Media Errors          | 23  | 8960 - 12543  | Errors related to the media on the network, errors are usually returned if your client uploads bad media files or for some reason there is an error related to the media content on the network.           |
+| Network Errors        | 31  | 12544 - 16383 | Errors related to actions on the network, peers not being found, posts not being found, incorrect permissions, rate limits, etc.                                                                           |
+| Server Errors         | 40  | 16384 - *(?)  | Errors related to the server, unexpected errors, servers related to administrators/moderators performing administrative tasks on the server                                                                |
