Bug 11802 - corrects for the patron purchase suggestions page

This patch corrects some errors with the staff client's patron purchase
suggestions page (members/purchase-suggestions.pl).

To test, apply the patch and make sure the patronimages system
preference is enabled.

- View the purchase suggestions page for a patron whose record has a
  patron image attached. The image should appear in the left-hand
  sidebar.

- View the page for a patron who has submitted no purchase suggestions.
  The message should be styled correctly.

- The toolbar on the page should look correct and work correctly.

Bug 11328 - Show local cover images in staff client search results

Local cover images do not appear in staff client search results. This
patch adds them.

To test, enable the LocalCoverImages system preference and add at least
one cover image to a title. Perform a search which will return results
that include your title. Confirm that the local cover image is
displayed.

Search results should also display correctly with and without
AmazonCoverImages enabled as well as with LocalCoverImages disabled.
