Soap, lube, and janitor tweaks

- The janitor cart can now be emptied by using a crowbar on it. It has a delay so assholes that try to crowbar your shit to dump it out can TASTE YOUR MOP before they get a chance to.
- Soap now has clean times like mops. Soap by default is slower than a mop. The captain's heart deluxe soap is the same speed as a mop. This will make janitor more fun and less 'le soap to replace janitor entirely'. Syndicate soap is faster than a mop and all the other soaps, because it costs TC and should have a practical use outside of slipping (cleaning crime scenes). Updated the description of the syndicate soap to reflect this.
- Buffed trash bag a bit to cope with the lack of disposal bins in main hallways (see below)
- **Lube nerfed to stun you as long as a stun baton (it previously had a longer stun than anything in the game barring stun papers)**
- Added advanced mop with twice the capacity of a normal mop for more cleaning before you have to wet your mop and twice the mopping speed, it can be made in research
- Added holosign projector to research (Janitor still gets it by default)
- Added holosign projector to janiborg

Regarding trash bags, I could not pick up any more cigarette butts once I reached this capacity:

...Which was really fuckin' lame. I'm not sure if the bag is borked or what, but a buff was in order because it certainly doesn't hold 21 things.
