Moves the light switch that affects every light -entire- prison wing from the perma-brig to a more reasonable location. Future solution: Look at creating more areas?

Virology now has emergency shutters on its exterior windows. No one likes a plague-carrier but seems rude to let people to due from lack of oxygen simply because a window breaks.
Of course.. helps if the light button is actually still in the correct area.
Don't tell anyone but I snuck in another distribution pipe fix.
