-Adds secure atmos closets to Atmos
-Removes a redundant check in water's obj reaction, add's a "cooling power" var that determines how effective it is at cooling off hotspots
-Modifies extinguishers a bit to have more options, affect more tiles, change the cooling temperature of the water inside of it, etc
-Makes the water backpack for atmos even more robust at fighting fires with a 5 tile spread, removes converting oxygen to nitrogen on Nanofrost, made the resulting end of a firefight annoying as the atmos tech would have to get an oxygen canister
-Makes racks use Move() to put objects on top of them instead of just changing the loc, in order to stop nozzles/misters from getting on them
Fixes some roundstart runtimes relating to set_species().
