Aliens are killable, ship is killable, ship jitter

Aliens are now killable! If a bullet collides with them they will die,
complete with a death animation. Ships also die in a similar way, except
the animation is called when they collide with an alien. The ship also
has a random x/y jitter to simulate real spaceflight
