Bug 33310: Use template wrapper for tabs: Suggestions

Bug 33310: Use template wrapper for tabs: Suggestions

This patch updates the suggestions template so that it uses the new
WRAPPER directive to build tabbed navigation.

To test, apply the patch and go to the suggestions page in the staff
interface.

- By default you suggestions should be organized by status, with a
  separate tab for each status (pending, accepted, etc).
- Use the "Organize by" form in the sidebar to change how suggestions
  are listed. In each case confirm that the tabs are redisplayed
  correctly.

Works as advertised. 3/3
