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. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@243 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
