Version 0.2.1 Released

New features:

• AI drivers added to the Bubba Prizes and Championship Rankings when playing with less than 3 players.
• AI drivers can now brake for hairpin turns (can't say they're good at hairpins yet... but at least they aren't hopeless on the Finger Lakes GP track now).

In other news, I believe I'll use the recently-demolished Wimbledon Stadium in London as the model for the final oval track (in figure-8 mode, of course) before moving on to the remaining 7 GP tracks.
