Added Raymath binding + Initial examples
- Added Raymath.cs binding. Raylib.cs depends on this since they both share some types. - Bindings moved into source directly. - Inital examples port alot of syntax still needs to be fixed. - Couldn't get cppsharp to work correctly so using a custom generator(WIP).
