5662: Show control number without organization code in OPAC URLs

5662: Show control number without organization code in OPAC URLs

OPAC detail xsl adjusted at four places: 773 when leader19=c, 775, 780, 785.

Enable the pref UseControlNumber when testing this patch. And set pref OPACXSLTDetailsDisplay to using XSLT stylesheets.
Test by adding a control number ($w) in abovementioned fields.
Go to opac detail and check if the links work.
Add some orgcode between parentheses or brackets in front of the control number.
Test again in opac detail if the links still work.

Works with and without orgCode in front of $w now.
No change to current behaviour, but closer to MARC21 standard.
