Bug 28347: Add DataTables, additional information to patron attribute types management

This patch enhances the display of patron attribute information on the
attribute management page.

To test, apply the patch and go to Administration -> Patron attribute
types.

 - If necessary, add multiple patron attributes so that there is data to
   display. Include:
   - Some which are mandatory
   - Some which are linked to an authorized value category
   - Some which share a class.
 - The tables showing your attributes should each have DataTables
   sorting and controls (except for column configuration, which isn't
   added by this patch).
 - Confirm that DataTable controls work correctly for each table.
 - The table should include columns showing authorized value category
   and whether the attribute is mandatory.
 - If you are logged in as a user with permission to manage
   authorized values, the data in the authorized value category
   column should be linked to that category on the authorized values
   page.
