Bug 26049: Replace li with span class results_summary in UNIMARC intranet XSLT

Bug 26049: Replace li with span class results_summary in UNIMARC intranet XSLT

In all XSLT for record display, fields are created with <span class="results_summary> except in UNIMARC intranet where there is just <li>.

This allows a better CSS customisation and closer code in files for OPAC and intranet.

Actually li gets diplayed with a dot at each line, we don't want this.

Test plan :
1) For each modified file run 'xsltproc file.xsl' and see there is no
   error
2) Use default XSLT in all system preferences
3) Perform a search and check display with and without patch
4) Click on a record to see details and check display with and without patch
