Upload #2, now with losing (and winning?)

I just hacked in a super gross pathway to notify the game that the player has taken damage, and now the player can lose. I suspect that the player can also win, but it takes a long time to get there, so that's only conjecture at this point.

TODO:

• radar display?
• repairs?
• health display?
• fancier scrolling notifications?
• more cars?
