AI driver

[thelusiv]

This is coming along nicely. Here are a few things I've noticed/questions I have:
* the lap timer is tripped every time the player goes around as well as every time the robot goes around. We need to set up some kind of timing tables class to put lap data in for each of the robots (as well as the players...this should eventually also work into the player profile).
* Why do some tracks work and others don't? Lots of the cars seem to work alright. I haven't tried them all yet.
* I get segfaults when doing pause -> restart game, pause -> leave game, pause -> quit.
* Will this system be able to accept other robot modules? Is it compatible with TORCS robots API?
* Both cars have bounding boxes so theoretically it should not be hard to do collision. Joe, any comments there?

Sorry for so many questions, I honestly haven't had time to look over the code yet, I have been busy since you added this, and testing the code is much more fun All in all the AI is a blast to play with. I like your latest improvements to the driving, they are not hard to overcome but still they can get a good bit ahead of you if you screw up.
