Procedural Generation of terrain / obstacles

[shiffman]

Now includes some extra obstacles but leaving this open b/c plenty of room for improvement!

One cool idea for procedural terrain generation would be different geologic layers that affect the steering bias. So when you're in a "hard" layer, maybe it doesn't turn as sharply (and so on). It could be a color lookup like the collision detection.

Yes! And nice wavy perlin noise layers! (I used this technique for a project many years ago, here's what it looked like!)

I think all but what spawned into issue #31 is already done
