-Change to mech drills, the regular ones mine sand just as they mine the asteroid walls (Meaning they mine a 1x3 area and stick it in an orebox)

-Asteroid floors cannot be burned into metal tiles anymore
-Added some better comments in the turf.dm as well
-Fixed Issue 329, so Triumvirate works again
