Bug 26085: Add the copy, print and export DataTables buttons to lost items report

This patch removes the in-page DataTables DOM configuration option so
that the default option is used. This will allow all the standard
controls to appear, including copy/print/export.

Since the default DataTables information includes the number of results
in the table, the template markup showing this information is removed.

To test, apply the patch and go to Reports.

- Run the "Items lost" report using parameters which will return
  multiple results.
- On the results page confirm that the standard controls are present:
  Result count, search form, columns filter, export buttons.
- Confirm that the "Activate filters" feature works, and that selecting
  results activates the option to download a CSV using a CSV export
  profile.

  Note that the "Activate filters" feature doesn't play well with hidden
  columns. However this issue predates the patch.
