Added RAW Loader. Tested with various configurations, seems to work.
Added OFF Loader. Tested with various configurations, seems to work. Added POLYLINE support to the DXF Loader. Added WIP version of the MDR loader - disabled and not yet working. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@145 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
