Bug 9644 - Replace YUI button on the suggestions management page with Bootstrap

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

To test, view the suggestions page and confirm that the "New purchase
suggestion" button looks correct and works correctly.
