Bug 9631 - Replace YUI buttons on classification sources administration page with Bootstrap

This patch converts the toolbar on the class sources administration page
to Bootstrap, replacing YUI button code with Bootstrap markup.

To test, view the class sources administration page. Buttons should look
correct and work correctly.
