Added irrmesh (Irrlicht Mesh Format) loader to Assimp. Works quite stable, but no lightmapping support yet. Removed tinyxml, replaced it with irrxml instead. Added an IOStreamToIrrXML wrapper. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@194 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
