Comment 10 for bug 1519055

Branch updated here, with Kathy's changes cherrypicked. I've added a basic javascript function for now which removes duplicate entries in the search box on the advanced form, which may be applied when other checkboxes (notably "Limit to Available Items") are checked/unchecked. It's not an ideal solution, but should work as enough of a stopgap until this code is refactored shortly.
