MorphOS/PowerPC changes

This is first code working on PowerPC systems.
I added some definitions to make everything working on MorphOS platform but I think we must setup how code should looks like.
Added:
- __NO_MUSIC - disable music (I have problems with music on MorphOS)
- __NO_FLC - I must finish and commit this package
- __NO_OPENGL - disable OpenGL support (some problems with GL, should be fixed soon)
- __NO_SHADERS - MorphOS OpenGL doesnt suppoer shaders atm:(
