Reverted the janitor closet to the old trashbag. (It does work, I fixed it up in r2557.)

A bunch of fixes for various stuff that's been broken about the bag of holding. It should work as intended, now.
Made wet floor signs fit in boxes.
Cleaned up the janitor's closet a bit.
Optimised the vault wiring a bit.
