Added a fax machine to send messages to centcom with.

* Formatting can be seen by admins
* HTML tags can be used in replies
* Replies are sent directly to the fax machine and have a fancy stamp on them
* Currently uses access_lawyer but this might change
* Currently only admin-spawnable because I can't be bothered to deal w/ map conflicts
