OgreImporter: Fix UV flip for binary meshes. Fix exception XML parsing when positions are declared in a previous vertex buffer than the currentl parsed one (that has eg. UVs). Remove debug prints from material parser.
OgreImporter: Remove old Ogre test assets from test/models-nonbsd/Ogre. These will be replaced by a proper set of assets that will test all functionality in both binary and xml form + materials.
OgreImporter: Add the new set of test assets from the Ogre3D SDK samples. Included Ogre3D license and a readme that explains in detail where they were copied and what modifications were done to them post copy.
