Bug 9619 - Replace YUI buttons on libraries administration page with Bootstrap

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

To test, view any the branches administration page and confirm
that the buttons to add a library and add a category look
correct and work correctly.
