Reimplemented using jquery, added OSS plugin to both interfaces. This is another case where having a /common directory used by both OPAC and STAFF would increase runtime efficiency and cut development time. Removed unused variables. I changed the OPAC .term color to match the staff interface, rather than being a second shade of blue. The highlight/unhighlight link is currently a bit bolder than its neighbors, but my styling choices are provisional. I expect the final tweaking of CSS to come from another more capable designer, like Owen. Note this patch may rely on previously submitted "Search.pm minor cleanup" patch.
