(GH-670) Search enhancements

- exclude broken packages - this only filters out packages with a
  failing test status. It won't filter results from feeds that don't
  have that information available.
- download cache available - this option will only return results from
  the community feed.
- approved only - this option will only return results from the
  community feed.
