Make a way to `asciidocify` YAML text properties before converting to JSON

[briandominick]

In several places, we will use JS/JSON on the very front end to display significant blocks of text drawn from YAML. It would be great if we could asciidocify this first, where applicable.

This probably means re-doing the jsonify Jekyll/Liquid filter, one way or another. Maybe an asciidoc-jsonify filter? Or, we could just use an include and iterate through the object and asciidocify as we go. That wouldn't be too hard or resource intensive.

A third option here would be to parse all these strings up front with Asciidoctor.js. I really don't know what would be involved with that, and it sounds like overkill on the frontend. Still a consideration as I start to investigate this ticket.

Okay, the solution became pretty obvious once I started thinking about how much more effort would be required to deal with this on the backend. The asciidoctor.min.js file is 757kb, which is not minuscule, but I think it's worth it for now. I don't think we'll ever need much more than inline formatting, so maybe this can be pared down.

Including the whole node_module at this time seems ridiculous, but maybe we'll add that sourcing in when we deal with #24.
