Bug 9406: ensure confirmation of patron renewal is displayed

When renewing a patron from the patron details page, ensure that
the "Patron's account has been renewed until XXX" is actually
displayed.

This patch introduces a was_renewed CGI and template parameter
to clarify the intent of the relevent template sections.

To test:

- Before applying the patch, renew a patron from the patron
  details page and verify that you don't see the renewal confirmation.
- After applying the patch, renew the patron from the details page
  and verify that the "Patron's account has been renewed until XXX"
  message shows up.
- Renew the patron from the checkout page and verify that the confirmation
  message shows up.
