Fixes #6130

The construction outpost now has an air supply and rudimentary distribution system.
Glass and wood stacks are filled to their max stack sizes, 50 and 32 sheets respectively.
Ghosts can now teleport to Z-level 4.

There are now special air alarms which do not broadcast their alarms. These are used in the mass driver areas to let crew know when it's safe to use them again.
These air alarms have also been installed in the Research isolation cells to finally allow scientists to check what's up, at least as long as they are in there or have AI assistance.
