Bug 20534: Floating toolbar when editing vendors

This patch moves the Save and Cancel controls on the vendor edit form
into a toolbar which sticks to the top of the screen as you scroll.

To test, apply the patch and Acquisitions -> New vendor.

- Confirm that as you scroll down the page, the toolbar with the Save
  and Cancel buttons sticks to the top of the screen.
- Test that the Save and Cancel buttons both work correctly.
- Perform the same tests when editing an existing vendor.
