-Including the .dm that I forgot from r4525

-Changed the air assimilation for ReplaceWithFloor() and ReplaceWithPlating() so that it doesn't count non-floors/non-space turfs against the average.
-Commented them as well
Fixes Issue 851
-Standardized AIbots a bit, primarily with vars, attackby(), emag() and such (Mostly excludes M.U.L.E.'s though)
-AIbots now have a maintenece panel on them, which can be opened after unlocking the access panel by using a screwdriver
-The bots are now repaired by opening the maint panel and using a welder
-Emagging the access panel will unlock it permanatly, and emagging it with the maint panel open will trigger the emag behavior
-Floorbots will actually pull up tiles when emagged, 90% to just pull up the plating (And add it to the tile stock), and 10% to replace the floor with lattice
-When destroyed, floorbots will actually drop all the tiles they have stored, not just 1
