Starting to add asteroids.
The current asteroids are randomly scaled a bit, and have a random rotation. Enemies avoid asteroids, but the player does not. Still need to port the avoidance logic to the Player class. Or need to create a "ship" class that can be reused by enemies, player, and homing missiles.
