Bug 7980: [SIGNED-OFF] Group search results tag input with other actions

This patch hides the tag input form in OPAC search results when
TagsInputOnList is turned on. An "Add tag" is added to the
"Actions" line. Clicking the link un-hides the tag input form.
A "Cancel" link hides it again.

The patch also moves the display of ratings to the bottom of
the list so that existing tags are grouped with the other
title details which are prefixed with a label ("Type:",
"Availability", etc.).

To test, enable the TagsInputOnList system preference. Do a search
and try adding tags from the search results list.
