Fixes Beepsky's patrol path

Fixes his patrol path. He now goes from the security hallway to the law
office, arrivals, EVA, escape, telecomms, cargo, law office, and back to
the security hallway instead of just rolling his pimp-ass wheels between
arrivals and security constantly. The problem was that the arrivals
beacon was set to make him go to "3-EVA," which doesn't actually exist.
The EVA beacon is called "4-EVA." Although now it looks like we can't
count as the patrol path jumps from 2-Arrivals to 4-EVA. Also fixed the
magical floating air alarm by the bar that I placed, since I still have
no damn clue how wall-mounted objects are done.
