Ability to include javascript plugins

[AdamHolwerda]

Maybe I want a Javascript widget on every page, or a React component. Maybe I'd rather generate a single page app than a multipage static site. One I thought of would be: "Generate write-good output too?"

Would put an extra link next to the title so you could open two windows one with the story, another with the write-good output. OR put it in the same file I don't know.
