Bug 11736 - Use new DataTables include in Koha news templates

Bug 10649 introduced a new include file for adding DataTables-related
JavaScript assets. This patch adds use of this include file to the Koha
news page.

To test you should have existing news items with varying creation and
expiration dates. Apply the patch and confirm that table sorting works
correctly for all settings of the dateformat system preference.

C4::NewsChannels.pm has been modified so that it now passes an
unformatted date to the template, where the KohaDates plugin is used to
apply the correct formatting. Sorting is based on the unformatted date.

Also corrected: Capitalization errors.
