Bug 35768: Show 'Used in' records link for results in cataloguing authority plugin search

To test:

1. Edit a biblio record
2. Go to the 100 tab and click the plugin launcher icon for an author
   tag i.e. next to 100$a
3. Search for an authority and observe the results
4. Notice that the number of times this authority has been "Used" in a
   record is now a link, and clicking it does a search showing those
   records.
