Subject: [PATCH] Bug 14272: Show single news item [alternative patch]

This is a new patch for this bug that shows a single news item on the
OPAC using Koha Objects (Koha::News).

To test:
1) Go to Tools -> News on staff interface, make a news item to show on
the OPAC
2) Go to OPAC
3) Notice news item shows and title cannot be clicked
4) Apply patch, refresh page
5) Notice title is now a link. Click title
6) Confirm breadcrumbs shows title of news item
7) Confirm RSS feed and OpacMainUserBlock are not visible
8) In the URL, change the news_id param to an ID that does not exist
9) Confirm that an appropriate error message shows
