Triangulation:

- FEATURE: Concave polygons are now triangulated correctly.
 - internal face order is ccw now, flipwinding part of converttolh flag
 - added test files for the various formats supporting such polygons

FindDegenerates: 
 - improved behaviour when processing polygons, more tolerant.

Obj: 
 - material files are now properly read using the given IOSystem 
 - redirecting some std::cerr calls to our logger 
 - spaces and tabs are now allowed at the beginning of a line 

Viewer: 
 - max smoothing angle for normals is set to 90 deg now

vc9-workspace 
 - added assimp_cmd, renamed some virtual folders to be sexier.
