Bug 4215 OPAC "Search for title in" can fail with trailing slashes in title

While configuring Search for Title In links, I found that some target sites
can't process an incoming title search if the title being sent has a trailing
slash.  If the same search is sent without the trailing slash, it works fine.  I
modified opac-detail.pl to strip off the trailing slash (and space) for titles
being sent to other sites.
