Bug 11881: Small improvements for the availability informations in the search results list on the OPAC

This patch contains small modifications to the template of OPAC search results.
Theses modifications affect the "Availability" line :
* Add a linebreak after each location.
* Add the text "Call Number:" before call numbers.

To test:

I) Apply the patch

II) Include the following test in the OPACUserCSS preference:

.searchresults .CommasWithLinebreaks {
    display: block; # block - line breaks, inline - all one line
}

.searchresults .LabelCallNumber {
    display: inline; # inline - display, none - don't display
}

III) Do a search on the OPAC

IV) Validate : check the format of availability informations for each search result (Breakline or "Call Number:" text).
