Bug 13083 - Hard-coded " by " in opac-tags.pl

The OPAC's list of a logged-in user's tagged titles displays title and
author, which for some reason are combined in the script into one
variable. I can't see any reason to do it this way.

This patch modifies the script so that title and author are passed as
separate variables. In addition, subtitle is now passed as well.

To test you must log into the OPAC as a user who has tagged multiple
titles, at least one of which should have an author and at least one
with a subtitle. View the list of tagged titles and confirm that this
information is being displayed correctly.
