Facets after results, then DOMinate them into place

Facets after results, then DOMinate them into place

We can use a media query in JavaScript to detect a given width and then
drop the facets into their left-hand column if needed; if the browser
window resizes, then potentially put the facets back on the bottom.

Also add a rudimentary "Refine these results" link at the top of the
page that is only visible when the facets are at the bottom to
facilitate navigation.
