- added mesh attribute and face append functions - added Int4 constructor - continued the blender exporter - fixed a bug in clean_filename which made it produce unterminated strings - renamed clean_filename to goat3d_clean_filename and made it extern - added call to goat3d_clean_filename in the mesh XML export code to cleanup ctm filenames
