moving right away, even before the next life(). Used in door crushing to
prevent people from inertiaing through. Checks for /obj/special/stop in loc
every move. Compared to the number of other checks, I don't expect this to be
an undo burden, but can be commented out in case of OH SHIT LAG under heavy
load.
Moves /area/entered to its own file.
Adds a new area var called has_gravity. Determines if floor tiles count for
movement control (planning on adding more, currently can only be badmined)
Adds a new mob var called lastarea that is updated with the area you're in every
time /area/entered is called. r2917
Moves /obj/special/stop into /obj/effect/stop.
Thunks people when gravity changes. r2918
