No more cold airlessness

[Dr_Bee]

Cold space is actually an ancient bug, the human code checks the temperature of the tile you're on (defaults to 0K) without paying attention to the amount of actual heat energy.

even more reason to change it then.

What made me suggest it is me thinking about nuke ops fights and how shooting an RPG chills the entire room and makes fighting a frustrating and unfun affair as it limits the amount of gear people can bring. You cant use cool heavy armor or anything besides a spacesuit, plus it makes escaping airless rooms harder than it should be. Airless rooms should damage you but shouldn't do anything to movement.
