BAYPORT: Duct Tape

This commit ports Duct Tape from bay, alongside a few other changes for
our own code.

Bay12 Features:
 - You can tape paper to.. anything basically, like a sticky note.

Changes from Bay12:
 - Tape is a stack now, and has 10 uses per roll.
 - The guitar recipe now calls for 5 pieces of tape.
