Added simple animal hostile aliens. Drones, hunters, sentinel (ranged), queen (ranged rapid), and empress (large queen sprites, even slower than the queen and more health, time for boss fights!)

Added a move delay var to hostile simple animals, so you can set the move_to speed easily. So far everything but the simple aliens use the default of 2.
