Bug 18484 - opac-advsearch.tt missing closing div tag for .container-fluid

Bug 18484 - opac-advsearch.tt missing closing div tag for .container-fluid

This patch corrects HTML validation errors by adding back a missing
</div> which was removed accidentally by Bug 9043 (2014!).

This patch also removes "border" attributes from <img> tags because the
attribute is obsolete.

To test, apply the patch and test the validity of the OPAC's advanced
search page. The only error should be one about 'Bad value
"api-server,"' which isn't really resolvable.
