new track: circuit de pau

I agree, our collision code seems to work OK for basic stuff, but the collision response seems somewhat poor. When I run into a wall I get knocked back very jerkily, if I drive straight into a wall i get thrown backwards and forwards very quickly. So I'm for just about anything that will give it a more realistic feel, and I know ODE is a very solid library that I don't think we'll have a lot of problems with.

So if you want to set up VDrift to use ODE, I'll happily help add support to SCons, autopackage, and whatever else I think this would probably be a pretty big improvement, might even help performance in some areas (though generally now collision performance isn't too bad).
