v0.5.0-M1 : The first milestone release

Finally, the first milestone towards SypherEngine beta!
A fair bit of changes have been incorporated into the engine:

Breaking

• All game objects will now need to provide an instance of InputHandler for inputs, can be null.
• The parameter in the render methods have been changed to a renderer instance instead (finally!)
• Entity class in module core renamed to GameObject
• removed getLogger from SypherEngine

Major

• Camera2D finally works xD
• Window event handling
• a dispose method added to the list of methods to be implemented, will be useful later on once a resource manager system is in place.

Other

• split the project into multiple modules
• added helpful links and link to CoC in the readme
• fixed some minor bugs
• added a few examples to the examples directory
• Added a Transform class
• Integrated GameObject with current ECS.
• made SypherEngine.logger static

Deprecated

• Component class deprecated for removal
• Rectangle2D boundary in the gameobject class is deprecated for removal
