GCI-33 - Revamp site footer

Can you move this above `bodyAppend`? `bodyAppend` can be used to load scripts that run synchronously, which will cause the browser to noticeably pause at those scripts while they load/run. This means the page may not render `aboutHTML` for a moment, which in general looks weird :)
