Re-introducing IratePirate's PR

Since IratePirate's PR has reached a block, I'm redoing the most
common-sense changes and including an extra thing or two :

- Add in missing cameras to latest changes. I hope I got them all
- Fix broken conveyor belt corner in Cargo
- Fix some of the wires and pipes under walls, notably near Cargo and by
the vending machines near HoP Office
- Switch the General Fabricator windoor so that Mechanics get to control
who accesses it, but can still make it public at a moment's notice
- Add Air Alarm to Viro Access
- Added in some reinforced tables to Perma to make prisoner escape a bit
harder. You can no longer pillage Execution and unless someone snuck in
a welder you won't be able to pull off the Perma hallway strategy since
reinforced tables are now in the way. Pull something more intricate or
serve your sentence
