Add IMeshBufffer::clone for buffer copies, use it in CMeshManipulator::createMeshCopy

Browse Source 
CMeshManipulator::createMeshCopy creates new meshes which have copies of the actual meshbuffers instead of copying everything into SMeshBuffers (which didn't support 32 bit or any of the other special features).
