Bug 9629 - Replace YUI button on patron category administration page with Bootstrap

This patch converts the toolbar used by the patrons
[category] administration to Bootstrap, replacing YUI button and menu code
with Bootstrap markup.

To test, view the patrons [category] administration page and confirm that
the button looks correct and works correctly.
