modules/rkt: introduce a rudimentary scenes editor

This adds a BBS-style interface for creating new scenes in a live
rkt session.

It listens on tcp port 54321 on localhost by default, just use
telnet to connect, the rest is fairly self-explanatory.

This is still early days, but it's a whole lot more than nothing.
