+ Added a IRender interface to abstract how the render should work
* Completely rewritten the Render class
* Reorganised Game's fields, and made some local
* Background image is now in Game
* Improved performance of ARGBColorUtil.composite(), at the cost of clarity (explained more clearly in the javadoc)
* Renamed ARGBColorUtil.composite() arguments, because I was even mistaking which was which
* Small profiling improvement
- Removed reload() from Game. It was pointless.
