Nerfs Hostile Lockdown

- Cost doubled to 40 CPU time.
- One use only.
- Resets after two minutes.
- Bolt-shocked airlocks will have their bolt light status unchanged (The
lights will be on unless turned off beforehand)
- Central Command announcement to make it even more obvious.
- Opening/Closing code optimized to reduce lag potential.
- Fire doors are now closed without activating the alarm, making them
much less annoying.
