Terrainity

I flattened the terrain “walls” that prevented players from driving off the edge of the world, but I never liked the look of it. I think a better design is shutting the car off when the player drives outside the test area (with a fence around the perimeter maybe). I imported a free skybox asset and I am happy with the results. Technically, this does not count against my feature freeze as one of my cards is “TestTown Improvements,” so I can throw this work in that bin.
