Added first working version of a MDC loader; no further features like compressed frames tested at the moment. Added config options for keyframe loading, this has been tested with MDL7 only (atm). Some refactoring, a few files are much cleaner and smaller now. RemoveRedundantMats step does now remove unreferenced materials.
