Bug 20779: Style refresh for patron detail page

This patch makes style and markup changes to the patron detail page
template in order to make the display of information somewhat more
compact and to increase the visibility of the edit controls.

To test you should enable the patronimages system preference. Apply the
patch and view the detail page for a patron.

- Check that the page looks correct and that sections like "Alternate
  address" and "Alternative contact" are empty when there is no data.
- Check that the "Manage patron image" tool works correctly.
