armory hardening, atmos trap, syndi sheets

- Changed west lvl2 door airlock to always be an airlock, so bot is more
likely to path through depot on red.
- Repositioned some syndie mobs so they won't spawn next to breakables.
- Added toxin tank and 2 possible falsewalls next to bathroom, to make
the plasma door trap significantly more dangerous.
- Moved one of the lockers in the comms console room so it cannot block
the other if both spawn.
- Moved turret in dorm room so it cannot end up shooting the lockers.
- Adds south-facing door to armory.
- Adds grenade launcher turret in armory.
- Adds passive vents connecting officer rooms in a cross pattern, such
that using explosives in officer rooms can result in the death of
multiple officers due to air loss.
- Made vault (armory) harder to break into. It now uses high security
airlocks. In addition, on peaceful mode, these are bolted.
- Reduced the self destruct countdown when robbing the depot on peaceful
mode. Still possible, but very risky.
- Fixed issue where admin deactivation of peaceful mode was reported in
logs as a robbery.
- Fixed syndi mobs yelling 'Intruder!' during delta.
- Tweaked bedrooms, beds now have syndi bedsheets and there's a separate
mini-bedroom for an officer.
- Tweaked comms room, now has better layout.
