Bug 13302 [Revised] Use CSS3 ellipsis for email address in staff client patron sidebar

This patch replaces the email address text overflow solution implemented
by Bug 3256 with a CSS3 technique: text-overflow: ellipsis

https://developer.mozilla.org/en-US/docs/Web/CSS/text-overflow

To test, apply the patch and clear your browser cache. Edit the primary
email address of a patron so that it is very long. View that patron in
the staff client (on the checkout or details page, for instance) and
confirm that the email address is truncated with "..."

Confirm that the link and the title attribute of the link contain the
correct, full email address.

Revision uses a percentage instead of a fixed width for email display in
the sidebar to accommodate varying sidebar widths. Also added: Handling
of all email addresses displayed on the patron detail page. Although
email addresses in the body of that page were not in the scope of the
original patch, it's a good improvement to include those as well.
