Rename IMeshLoader::setPreferredIndexType to setIndexTypeHint and give it a new enum.

Browse Source 
Giving the loader it's own enum allowed me to add more options. 
EITH_OPTIMAL which reduces buffers back to 16-bit if they don't need 32-bit.
Using that in obj loader.
Also 32-bit meshes with EMT_PARALLAX_MAP_SOLID material should now work in obj loader (untested as I got no test-case)
