/libram command, with autocomplete, for documentation

[horrible-little-slime]

Libram generates its own docs, and prints them here. It would be nice to adapt that into an API.

Another issue is best exemplified by this page--the existing docs will expand out various named union string types, making some of this documentation unreadable.

But it'd still be nice to be able to /libram AprilingBandHelmet to display the functions in that module, and their type signatures.
