Title: LoaderOBJ added alpha support & fixed group hierarchy

Fixed 2 issues with my last LoaderOBJ commit. It now loads the full group hierarchy and collapses empty groups (some exporters use the 'g' tag to represent objects). It also loads materials with an alpha component and calls Object3D.setTransparent(true) when the object's material has alpha<1.0.
