Re-arranges areas

Less emergency shutters dropping due to alarms in adjacent but connected rooms. Primarily affects security due to previously overwritten changes.
The primary hallway areas are now less jagged, making alarm flashing look better during fire alarms/emergency shuttle calls.
Replaces the chief engineer/head of security areas with the existing crew_quarter variants as these are rad-storm protected (and are likely to contain SSD crew). Medbay break room moved into the crew_quarter type.
