Bug 17417 [Revised] Correct invalid markup around news on the staff client home page

This patch fixes two minor errors in the markup around displaying news
on the staff client home page: Adding a missing "class" attribute, and
changing the container around news items from <p> to <div> (because news
items might contain <p> and nesting them is incorrect).

To test, apply the patch and view the staff client home page with news
items showing. Validate the page and confirm that there are no errors.

Revision for QA removes an extra </div> from elsewhere in the template
to make the validator return no errors.
