Fix #1078: Citation not styled properly (#1080)

* Fix #1078: Citation not styled properly

Turns out our demo docs werent being rendered by sphinx as citations so this may have slipped though the sphinx 2 fixes.

I updated the demo docs and included the need style fixes.

* Group citations and footnotes

* Build Assets

* Build theme.css with "Fix #1078: Citation not styled properly #1080"
