Bug 11255: allow "relevance ascending" as a sort option

Browse source 
This patch fixes a problem where if a staff member sets the
*defaultSortField/*defaultSortOrder system preferences to relevance
ascending while QueryParser is enabled, default keyword search
would break -- the query parser config did not declare relevance asc
as a possible "modifier".

Note that setting the sort order to relevance ascending does not
actually make catalog search return results with the least relevant
records showing up first; Zebra does not support such a mode.  In other
words, relevance ascending acts exactly the same as relevance descending.

Test plan:

0/ Create some biblio with "history" in the title and
   ensure that the QueryParser system preference is enabled.
1/ Define prefs defaultSortField = relevance and defaultSortOrder = asc
2/ Search "history" on the staff interface
3/ Note that no result is returned.
4/ Apply the patch
5/ Verify the queryparser config file in use takes the modification into
account (see the queryparser_config value in your $KOHA_CONF file).
6/ Relaunch the search and verify results are returned
