The Actions > Page URLs and Page titles reports should have pagination

[matt]

Because the reports are truncated after 500 rows by default (see config value datatable_archiving_maximum_rows_actions), there is more to display than what is currently displayed in these reports.

We should either

• quick fix: display all rows, but this will significantly slow down the page load
• proper solution: Add pagination the same way it works with standard datatables.

(In [2339]) Fixes #1428 Page titles, Page URLs reports now have pagination like other datatables.
