Bug 7876 - Add ids to divs and spans with ids in opac-user.tt

This commit adds an id to each div, and adds spans where
there are no appropriate divs to add. In addition, non-static text
such as the expiration date are wrapped in a special sub-span so
that data can be pulled and reused when customizing via jQuery.
