IMeshLoader can now set hints to prefer 16/32 bit buffers. Obj loader can now load 32 bit buffers.

Browse Source 
- 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.

--------------------------
Changes in 1.9 (not yet released)
- obj meshloader can now load 32-bit buffers when setPreferredIndexType is set to EIT_32BIT.
It's 16 bit meshes use now also an IDynamicMeshbuffer instead of an SMeshBuffer.
- Add IMeshLoader::setPreferredIndexType and getPreferredIndexType to allow setting hints for the loaders if users prefer 16 or 32 bit meshbuffers.
- Add IMeshBuffer::getType to allow finding out which class type a meshbuffer has (similar to ISceneNode::getType).
- Add IGUIImage::flip to flip/mirror images
- IBillboardSceneNode got functions to access meshbuffers. So uv-coordinates can now be modified directly (previously only possible via texture matrix).
