Title: #667 Don't display a facet with only one result.  

#667

If a facet has one result, hide it, it's redundant data. Since OS knows to hide blocks that have no content, just remove the block content if the facet result count is less than or = to 1.

Also cleaned up the Filter by post date to match the text casing of the other facets.
