Nerfs Hostile Lockdown.

This power's original intent was to slow down the crew such that the AI had time to respond to mounting threats against it.

It would seem that it is *too* effective in this regard, and when paired with plasma, would wipe out nearly the entire crew in mere minutes.

I bear full responsibility for any rounds ruined though this feature.

- <b> Airlocks are no longer shocked.</b>
- Cost doubled to 40 CPU time.
- Bolted airlocks will have their bolt light status unchanged (The
lights will be on unless turned off beforehand)
- Opening/Closing code optimized to reduce lag potential.
- Fire doors are now closed without activating the alarm, making them
much less annoying.
- Short cooldown introduced for performance reasons.
