Create an interactive glossary of common terms and acronyms

[melchoyce]

Hello!

I'm a new member of 18F and I've been working my way through the Handbook. One feature that I think could be helpful is creating an interactive glossary of common terms and acronyms. Ideally, any time a word in the glossary appears in a page, it's given a style that indicates it's interactive and mousing over or tapping the term opens a popover with the definition:

Dark Popover	Light Popover

You can see the glossary that inspired this issue on the "Make WordPress" blogs:

(For reference, the code lives here: https://meta.trac.wordpress.org/browser/sites/trunk/wordpress.org/public_html/wp-content/plugins/handbook/inc/glossary.php)

Appreciate the consideration!
