Burglar Alarm for Captain's Display Case

-Breaking the Captain's Display Case will now trigger an alarm, bolting all airlocks in the room as well as notifying the AI (after a 3 second delay)

Nowadays, I'm seeing far too many Captains breaking their display case with little repercussion. Keeping the gun in the case used to have value when the AI was able to watch over it (hear people breaking it), but since the AI was moved there's no value in keeping it in there besides avoiding accusations of powergaming.

This change is meant to add incentive for Captains to keep it in the case (Extra Security), humiliates them for taking it in non-emergencies (bells and whistles will draw everyone's attention), and makes the steal objective a little more unique from the other ones.

Traitors would need to secure their own escape route first, or risk being extremely predictable and jump down the disposal outlet. 

An alternative to bolting the airlocks, should this be seen as being too extreme, would be to simply drop firedoors instead.
Done and updated. I moved all the related area checks into these procs, too, so it doesn't need to be done every time you want to start a fire alarm.
