Bug 9463 [Revised] Use DataTables on patron sent notices page

Replace the tablesorter plugin with the DataTables plugin on the
patron sent notices page.

This patch adds default sorting by time (descending).

This patch depends on the one for Bug 9887, which introduces a new
DataTables plugin to allow sorting on data embedded in a <span>'s
"title" attribute. This allows sorting to be done on an unformatted
datetime.

To test, open the sent notices page for a patron who has multiple sent
notices. Confirm that table sorting works correctly with various date
format settings.

Revision corrects an error which occurs when there are no notices:
Instead of displaying an empty table with a message the table is not
displayed and a standard dialog message is displayed. In order to
prevent page-specific CSS and JS from conflicting with the standard
"message" class the page-specific classes have been changed from
"message*" to "notice*" Test this change by viewing a page with existing
notices and clicking the titles to show/hide the notice contents.
