Jared Camins-Esakov 44cd5e058b Bug 8205: Add OPACShowUnusedAuthorities syspref
Rather than list authorities that are not actually used by a library,
this commit introduces a new syspref: OPACShowUnusedAuthorities to
enable libraries to hide unused authorities in the OPAC authority browser.

To test:
1) Do a search in the OPAC authority browser that brings up multiple
   results, including some that are used in the bibliographic database
   and some that are not.
2) Observe that the results include both used and unused authorities.
3) Set OPACShowUnusedAuthorities to "Do not."
4) Repeat the same search as in step 1.
5) Observe that the results no longer include unused authorities.

Signed-off-by: Katrin Fischer <Katrin.Fischer.83@web.de>
Preference is implemented cleanly and works like advertised.
As a note: The unused authority records will be hidden from display,
but the result list paging does not adjust for the hidden records.
So the result pages will show more or less records total, depending
on how many records are hidden.
