Bug 10218: Add individual CSS classes for bibliographic information in OPAC (UNIMARC)

Bug 10218: Add individual CSS classes for bibliographic information in OPAC (UNIMARC)

Follow-up for UNIMARC XSLT Display
This patch adds class to span markup in list and detail display.
XSLT are not build in the same way in MARC21 and UNIMARC, so I had
to add a parameter "spanclass" to 3 templates called in UNIMARC :
tag_title, tag_7xx, tag_comma

To test, apply the patch on a Koha instance with UNIMARC records, and
- activate sysprefs  OPACXSLTDetailsDisplay and OPACXSLTDetailsDisplay
- make a search on the OPAC. In the results, check the spans with
"results_summary" class have also more a precise class.
Ex : span class="results_summary publication"
- view some records in detailed view. If possible, a record with
a series, a record with some subjects, a record with different authors,
a record with a link in 856. Check the spans with "results_summary"
have also a more precise class.
