Bug 19643: Pagination buttons on staged marc management are stacking instead of inline

This patch modifies the template for staged MARC import management to
correct a problem with the style of pagination links.

To test you must have more than 25 staged imports. Go to Tools -> Staged
MARC management. The pagination links, both at the top and the bottom,
should look correct (use multi-page SQL report results for reference).
