FacetAPI Quicklist

Adds an 'All' link at the top (if viewing the top level) or second (if drilled down, that is, below the selected facet).

This link is equivalent to resetting the current facet (or all current facets if you can link to more).

This makes it very easy to style the resulting facet links list as a drop-down with CSS, with the currently selected facet always visible.

The 'All' text can be changed to whatever you want.

Further provides an option to change the way one of your facet displays work, to add in all terms (an implementation for non-taxonomy-term facets has not been attempted, sorry). Showing only current facets is how facets usually work (this is the default). Adding in missing facets will show those links that normally wouldn't be visible, because we've drilled down— they'll be shown without a count in parenthesis, since they are currently zero but clicking them takes you out of the drill-down, but the facets that would normally be present are shown with a count in parenthesis and clicking them drills you down further. As that can be a bit confusing, the final option is to replace facets with a top-level listing, without counts, that always applies only that facet and removes any other filtering in place.
