[MAP] Air/Airless Cleanup

-Fixes aired/airless turf mixing -- Most at the mining asteroid alien base, and a few stray tiles at the derelict and telecomms satellite.
-The little hydroponics room in the mining asteroid has its hydroponics trays removed. Instead, there's a sandstone stack for making dirt growing trays, along with some extra botany supplies.

-Adds a damp rag to the bar, and a blender to hydroponics, in line with the metastation equivalent.
