Thumbscrew Nears a b3

I did a lot of work on Thumbscrew here at PyCon, and it’s really paying off. I’ve got the two subprocesses churning stuff out now, posting notifications, which the main program uses to update the display and progress indicator. I had to rip out quite a lot of code to get down to a simple reimplementation, so the Preferences stuff is all broken right now. This is actually okay with me, since I’ll be using an NSUserDefaultsController to map the preferences into the UI, rather than hand-wiring all the outlets and actions. So it was going to need to be rewritten, anyway.

Now, when you accidentally drop your whole iPhoto Library onto Thumbscrew, you can stop it at any point. Hurray, coming soon to a desktop near you.
