Merge pull request #4561 from LordFowl/kneejerk_revert

Fixes some dumb mapping decisions made in dev:

Mining is no longer surrounded by perfectly clean tiles.
Paramedic ladders no longer look like ass.
CRYO IS SYMMETRICAL NOW JESUS FUCK
Removed the lightbulbs surrounding mining. Added some spotlights to the front-door of mining.
Fixed the industrial decals so they were no longer on asteroid turf and now they are no longer as glitchy
