Syndicate teleporter fix, fix fire alarm in engineering that gets EMP'ed

Changes:
1) Removes the fire alarm close to the singularity, that keeps triggering due to the singularity's EMP.
2) Syndicate beacons can no longer be locked on to. Emagging the teleporter console allows you to lock on to them again. Beacons can be emagged so they're set as a syndicate beacon.
