Bug 9688 - Replace YUI button on Authority MARC framework toolbar with Bootstrap

This patch converts the toolbar used on the Authority MARC framework
toolbar to Bootstrap, replacing YUI button code with Bootstrap markup.

To test, view auth_tag_structure.pl for any authority framework. Confirm
that the 'New tag' button looks correct and works correctly.
