Bug 23122: When searching callnumber in simple search, search option is not retained

This patch copies some code and markup from the staff client where call
number phrase searches are correctly handled. A check for
'ms_callnumcommaphr' is copied from search_indexes.inc. Handling of
commas and dashes is copied from search.pl.

To test, apply the patch and make sure the
OpacAddMastheadLibraryPulldown system preference is enabled.

 - From the OPAC main page, select "Call number" from the search pull
   down at the top of the page.
 - Perform any search (it need not return results).
 - Verify that the search option retains the "Call number" selection.
 - Repeat the test with and without the OPACNumbersPreferPhrase system
   preference enabled.
