Created a backend system for the window-input management. So now it will be a los easier to port to another windows library/platform.
Since this is a big commit, it's probably that some bugs where introduced, but i tested all that i could, and it's working fine.
I'll probably add a cursor manager backend because right now there is no cursor management at all, i removed the CreateCursor function because it was unusable.
Added GetWidth, GetHeight and HasDepthBuffer methos to cFrameBuffer.
Added settings.hpp for the physics engine, and added some options to define.
Added events to the UI Window buttons.
Now the batch renderer is enabled by default ( before was forcing the renders always ). So i fixed all the bugs around this.
Fixed a bad texture rendering when tried to render in isometric mode and a sector of a texture.
Added some functions for tex env managing.
Modified some enum names from renders.
Added a pixel separator for characters in the ttf creation ( optional ).
Moved some OpenGL and GLEW things to cGL, this is for a future implementation with OpenGL ES and without GLEW.
Tryed to fix a bad rendering bug when clipping controls with borders ( borders disappear ), i think that the hack is working.
Modified some name conventions.
Added a Memory Manager to trace memory leaks.
Fixed some memory leaks detected with the new memory manager.
Added an allocator for STL ( to use it with the custom allocation seted in the memory manager ).
Fixed Makefiles ( i wroke them ).
