Big improvements and modifications

Improvement:
- Add SoundManager (not 100% finished yet)
- Add init(Engine engine) in GameObject
- Add ButtonBuilder (to create Button)
- Add onClickExit() in the ButtonListener

Modifications:
- SceneManager.scenes is now in static
- FontLoader.getDefaultFont // FontLoader.getLoadedFonts is now in static
- Entity don't need Engine to be declared
- Reorganised InformationsPanel and not need Engine
- Reorganised SplashScreen and not need Engine

Bugs fixed:
- MouseListener bug with buttonsPressed fixed
