Ice colony elevators access

[Jaketeaking]

Summary (a quick, 2-3 sentence summary):
make the ice colony elevator doors open when its at a station
Benefits (How this will benefit the server and game as a whole):
prevents atmos attacks when marines have to C4 the doors because there are no engineers
makes the elevators actually useable
you dont have to all lay down to let the engineer at the back to hack the doors again because they didnt open at the other end.
Details (Description of how you think this would work, the benefits, etc):
basically as summarized, both sets of doors on the elevators open at the top or the bottom, depending on when the elevator is there
Implementation (Optional, if you have an idea how to implement it):
assume it would be something to do with triggers
