Just so no one else wastes time, I've added the vertex groups and scaling to the blender obj import. Limited tests, but looks good.

I've written a provisional, untested patch for SH3D that I think will do the "o" entry. I'm not a Java dev but can sort of understand it, so it looks correct. I don't yet have Eclipse/JDK installed in order to try building it. That's the next job.

After that (if can figure it out) I might try and implement the idea of putting imported objects into a tree of blender containers based on Level and furniture groups (idea 2 in my earlier message). No promises on that one though.
