TG: Adds a new special object (stop) that can be used when you need someone to stop

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
