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)

- IMeshLoader::setPreferredIndexType and getPreferredIndexType allow setting hints for the loaders if users prefer 16 or 32 bit meshbuffers. Loaders are free to ignore those hints (all but .obj will do that for now).
- obj meshloader loads now 32-bit buffers when setPreferredIndexType is set to EIT_32BIT.
NOTE: It's 16 bit meshes use now also an IDynamicMeshbuffer instead of an SMeshBuffer.
That will break the code of people who accessed meshbuffer before by casting to SMeshBuffer*
And might even be somewhat slower (lot's of virtual functions...), but shouldn't really matter and can maybe be a bit improved.
Sorry about that, I considered keeping SMeshBuffer for 16-bit (still considering it), but it would add some overhead in code and I don't think it's worth that. If there are any complains I'll maybe consider it again.

mtllib commands previously used only the first word, now they use the rest of the line.
Different obj format descriptions describe the mtllib command in 2 different ways:
- http://paulbourke.net says it can load several mtl files separated by spaces
- Wikipedia says it can load one mtl file (but there can be several mtllib commands)
We previously loaded 1 file - using the name up to the first space character, so it basically was not correct for either solution. We now go with Wikipedia, because it allows using space in filenames and I tested several other tools and they all handled it like this.
Also COBJMeshFileLoader::copyLine no longer copies the newline character (didn't do that always anyway and we don't need it)
