Bug 33575: Add dataTable to hold table on /reserve/request.tt

To test:
1. Have a record with several holds on it.
2. Go to the holds page for that record ( /cgi-bin/koha/reserve/request.pl?biblionumber=144 )
3. Cannot sort by columns
4. Apply patch, restart_all
5. Now the table should be a dataTable that will allow you sort.
6. Try hiding columns by clicking on the 'Columns' icon above the table, make sure columns are correctly being hidden.
7. Try to hide columns by going to Adminstration > Table settings ( Circulation > Holds > patron_holds_table ), make sure columns are correctly being hidden.
8. Now login with a user who has the 'place_holds' permission but does NOT have the 'modify_holds_priority' permssion.
9. The table will not have the change priority columns. Make sure all columns can still be hidden/shown correctly for that use.
