Version 0.2.2 Released

New features:

• AI cars can now pitstop when needing repairs.  Not all AI personalities will choose to do so, however.  I can't say they're terribly smart about it yet... and it can be a bit humorous to watch them trying to figure it out with the wheels they have left.

Given that racing against just the AI seems to get most interesting after 15 laps, I'm considering opening up the longer race options on the demo version.  I haven't done so yet.  Just considering it.
