2nd big refactoring.

Goals are orthogonal components for:
	- OS Windowing system
		- NEWT, X11, Windows, MacOsX
	- GL Windowing GLUE
		- EGL, GLX, WGL, CGL
	- GL profiles
	- core and util packages
	- generate all Java components from any platform

All above goals are achieved.

TODO:

- Native compilation fix and test
- Check/Fix Win32, MacOSX and the mobile devices
- ..
