ASE and 3DS cleanup - face ordering improved.

Further work on target camera animation support in both loaders. Some general animation problems in both formats remaining, too. 
Added GenUVCoords and TransformUV-steps (see ML). The latter has been fully implemented, test file are there. GenUVCoords is a dummy for the moment.
Boost workaround for shared_array.
Further work on the documentation.
Updated material system (see ML).
Bug fixing in the AC loader, lights are now supported, too.
