Scrubbers and cameras

Security had a few scrubbers turned off by default. Is corrected.
The security lobby no longer has a 2-3 layer reinforced table, strengthened with random scrubber pipes.
A vent change in medbay was lost, causing a room to have two vents. One vent has again been relocated into a hallway without one.
Some area and camera changes (virology primarily) were lost in recent merge. Restored.
Some additional camera movements to kill a last stray spot in security.
