Fax Machines

Fax machines are now a subtype of photocopiers and as such can send papers, photos, and paper bundles.

Also a bunch of photocopier cleanup: Removed unnecessary vars, absolute paths, etc.

- [x] Local testing: Sending/receiving papers, photos, and bundles, viewing and replying as admin.

~~- [ ] Received message queue for when the machine runs out of toner.~~
~~- [ ] Fax covers/templates.~~

- [x] Remove interdepartmental message delay.
