Restore facet-first loading, add breakpoint for results

Restore facet-first loading, add breakpoint for results

Facet first loading should be faster on slow servers, so do that rather
than loading them after the results and forcing a page render when we
dump them into place on wide screens.

Also add an 800px breakpoint to prevent results from getting pushed
underneath the facets; at 800px, we go into "hide facets" mode instead.
This gets picked up by the 600px breakpoint, so it's all good.
