Implement More BBCode for Paper

[CameronWoof]

Currently, my bureaucratic hellhole (the Customs Desk) is woefully under-realized because there's almost no formatting available on paper. Other stations have tons of formatting options (including FIELD, which solves the problem of making blanks too small or having weird underscores left over after the text) and centering/layout options.

Also, does the SIGN code actually do anything other than put your name in? It should probably be in a unique font so that people know you actually SIGNed it rather than just someone wrote your name on the paper.
