Cleaned up the layout of the facet links in the side column. Added a close, "X" icon and red, hover background highlight to the selected faceted links in the results table header. Removed the " - " from the "Sort By" menu, that is no longer necessary now that "Sort By: " is a label outside the dropdown and not an item within the list. [ref 2656]
