Jared Camins-Esakov 8471158160 Bug 8209: "Did you mean?" from authorities 
One of the ideas behind authority records is that users who search for
one term should have related terms (according to the authority file)
suggested to them. At the moment, Koha doesn't do that. Adding an
authority searching step to regular searches and displaying any
suggestions in a "Did you mean" bar at the top of the results would be
very useful.

This commit adds a Koha::SuggestionEngine class which is in charge of
getting suggestions from individual suggestion engine plugins, which
much be in the Koha::SuggestionEngine::Plugin::* namespace, and extend
Koha::SuggestionEngine::Base. Suggestions are loaded asynchronously
using AJAX, and a link to a page with suggestions is provided for users
with Javascript turned off.

The AuthorityFile suggestion engine plugin looks up the specified search
terms in the authority file and then suggests searches for records using
matching authorities.

Test plan:
- Verified database update added system preference correctly,
  pref defaults to OFF
- Verified search results and detail pages in OPAC and staff
  still worked the same as before
  * for no results
  * with results
- Activated system preference and tested various searches
  * Searches from simple search
  * Searches from advanced search
  * Search links in records
- Deactivated Javascript - verified fallback works correctly

Notes:

- Suggested terms can include autorities with no linked records.
- When combining more than one search option using advanced search
  this results in "no suggestions" more often. Feature works best
  from simple search.

Overall great feature making use of authorities in a user friendly way!
