Bug 23656: Add cataloguing search bar to addbiblio

This patch adds the search header to the cataloging editor page. With
the staff redesign, this takes up very little space, so I think can be
added and visible by default

To test:
1 - Apply patch
2 - Load the basic cataloging editor for a bib
3 - Note lack of search bar
4 - Apply patch
5 - Reload the page
6 - You have a search bar
