SimTool

SimTool runs. Adds the small bit of extra setup needed for this stuff to the script. [Also, the setup script had some old weird bloat, so I took that out.] To test: install libeigen3-dev. Then do "make sim" in the tool directory. You should get a vision sim tab with two simulated images and some controls. Move things around and make sure the images look sort of reasonable. Mostly, just make sure I didn't mess anything else up. This code should be there for the future, but it's not exactly crucial.

SERIOUSLY test this. I'm running it all on 64-bit Ubuntu 13.04, so it may all explode on a more typical nbites machine.

Also make sure I didn't add in anything too weird. I think I took out all the clutter from this getting moved around in git so much, but no guarantees that I didn't make a mistake.

Some things could be improved, mostly the GUI and how it fits onto the screen and how this code interfaces with other nbites stuff. A lot of it is completely self-contained, when really it should get its constants etc from the main code base. Newbie projects? Or maybe I will suddenly have tons of spare time and fix it myself.

And I didn't write this all on one day in February. The git history is kind of messed up.
