Bug 19949: Update popup window templates to use Bootstrap grid: Cataloging authority search

This patch updates the cataloging authority search templates to use the
Bootstrap grid instead of the YUI grid.

To test you must have a MARC subfield configured with "Thesaurus"
linked to an authority type.

Apply the patch and go to Cataloging -> New record. Click the plugin
link for the field which is linked to authorities. In the popup window,
the search form and search results should look correct.
