[Koha] Show responsibility statement (245c) under title and move authors down in OPAC XSLT

Hi all, I added report http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=9490 in Bugzilla for showing the responsibility statement under the title for opac detail and opac results. If you would have any feedback on this, please add to the discussion under that report. Thanks, Marcel
