[MAP] Asteroid changes

You can no longer power machines on asteroid turf; IE: Dragging the AI onto it will cause it to slowly die, and you can't run rechargers on it. Outposts are unchanged.

West mining-broken-up-fields have been filled in, and turned into normal mineral spawns instead of high chance, to stop MLG PRO MINING from finding diamond in the first 4 minutes of the round at a 100% rate. The high chance mineral tiles have been dotted throughout the asteroid, to encourage exploration.

High chance and Labor mineral turfs now have their own icon, to more easily differentiate between them when mapping. They swap back to the standard rock icon on New().

*This doesnt affect recharge plates for mechs and the like, don't worry
