Bug 16551: Display the name of lists to the search results at the OPAC

This new enhancement will allow to add the name of lists containing a
biblio to the search results at the OPAC.

Test plan:
0/ Regenerate the css file to get the style change:
 % lessc --clean-css="--s0 --advanced --compatibility=ie7"
   koha-tmpl/opac-tmpl/bootstrap/less/opac.less >
   koha-tmpl/opac-tmpl/bootstrap/css/opac.css
1/ Create some lists and add items to them
2/ On the search results you should see the name of the lists which
contains the record.

Note that we could add a syspref to make this new behavior optional.
