Subject: [PATCH] Bug 33217: Allow specifiying sort field and order for authro
 links

When using the facets for author, i.e. limiting a search, it makes sense to preserve the default sort order for the results (relevance, etc)

When clicking on an author to search the catalog for all works by an author, it would be nice to be able to optionally specify sorting for the listing - i.e. publication date, or title

This patch adds two new system preferences:
AuthorLinkSortBy
AuthorLinkSortOrder

To test:
1 - Do a search in intranet and staff for 'austen'
    or an author you have multiple titles from
2 - Click the linked name
3 - Note a new search is performed, sorted by field from
    defaultSortField  preference
4 - Apply patch, updatedatabase, restart_all
5 - Ensure nothing has changed by searching again
6 - Set AuthorLinkSortBy to 'date of publication' and
    AuthorLinkSortORder to asc
7 - Search again, comfirm links obey sorting specific above
8 - Test other values - confirm links are updated in both staff/opac
    and results/details
