Working on 0.8.0 compatibility

[Windcatcher]

I'm slowly making progress. I think I've got bumpmapping perfected in the engine, and I've been slowly upgrading some of the mesh library objects and zones to use it. I might take a look at the shader this afternoon to see if I can speed it up, but otherwise it's working. My dynamic lighting shader broke use of tinting like infravision and such, but I don't think that will be hard to fix.

On the SimpleClient front, I've fixed the weirdness I was seeing with player and mob positioning. It was the old reversed-X-Y issue rearing its head, and all it took was correcting my Titanium packet definitions file. I also have it using my upgraded engine, though now I have to upgrade the client so it actually uses all the extra bumpmapping stuff. That isn't trivial, but it's otherwise pretty straightforward.
