Security remodeling again

It got generally decent approval in the thread. Two months ago.

Things that I want feedback on
-sleeper: Possibly too useful, concerns that it lessens the need for medbay
-armory: Shit design? Should the hardsuits be ditched? I feel that it's easier to break into/loot yet easier for the warden to set up defenses WHEN NECESSARY by wiring and bolting shield generators into place
-3 tile hallway: Some people disliked it

I read pretty much everything in the threads and everything here http://bugs.nexisonline.net/projects/vgstation13/issues
