Major changes to OpenGL render states. Should reduce the number of state changes and reduce some render state confusion. Also changed back the order of 2d texture setting and render state changes.

Compiling without the BMP loader now compiles without the built-in font data. Added some comments and a warning about this. CGUIPanel draws background when border is on

Fixed a problem with index duplicates which refer to different meshbuffers. Only fixed for non-animated meshes, yet, but might be not a very common problem anyway.

Major update to LWO loader to support more material properties and work with more meshes. Changed some meshloader constructors to take scenemanager instead of other parameters. Fixed obj loader texture loading with mixed file separators.
