Bug 26262: (follow-up) Fix course details page, default configuration

Bug 25287 changed the default DataTable configuration in the OPAC so
that tables are paginated by default. This is inconsistent with the way
we currently use DataTables in the OPAC, and the change was probably
unintentional. This patch returns the default pagination configuration
to what it was before: Off.

The patch also updates opac-course-details.tt with the same DOM
configuration as opac-course-reserves.tt.

To test, apply the patch and view the list of course reserves and the
list of titles attached to a course. In both cases there should be no
pagination controls, and the tables should show all results.
