Removed a bunch of copy pasted code regarding moving pulled atmos by clicking on turfs or conveyors. Now this is handled by a mob proc, Move_Pulled()
Now all turfs work with this feature. (shuttle shitty turfs didn't because they were not part of /floor)
Added a check on Move_Pulled() to see if the pulled atom is on a turf. This will stop the sleeper exploit and others.
A world << "" passed, deleting it. Sorry.
Merge pull request #837 from Aranclanos/Sleepers
