Subject: [PATCH] Bug 27766: Hide expired news items by default

This patch modifies the news page in the staff interface so that expired
news items are hidden by default. A checkbox in the sidebar can be
checked to show the hidden rows.

To test you should have multiple news items, some expired and some
unexpired.

 - Apply the patch and go to Tools -> News
 - The table of news items as it initially appears should not include
   any expired news items.
 - In the sidebar, check the "Show expired" checkbox.
 - The expired news items should now appear.
