Asteriods are now randomly shaped polygons. Disabled collision
detection until re-implemented.
Changed draw_asteroid to use GL_TRIANGLE_FAN.
This fixes the problem with drawing concave polygons.
Collision Dection works again. (Sort of)
Need to do polygon on polygon hit detection for ship.
Currently "hits" on center of ship, allowing the ship to get
partway into asteroids.
Asteroids move! Colored green for testing.
NEED TO FIX:  Polygon draws across window when points pass window threshold.
Asteriods now move in and out of window smoothly (mostly).
Fixed memory lea.  Credit goes to Douglas "The Douche" Otstott.
Ship now becomes invincible for a brief period after death. This allows
the player to move even if an asteriod was hitting them at re-inititialization.
Blinks aqua and white to let player know.
