Subject: [PATCH] Bug 14272: Show single news item (OPAC)

This change makes the news shown on opac-main-pl have
clickable headings which shows just that news item in isolation.
This is to allow further patches that adds commentary functions.

Sponsored-By: Halland County Library

Test plan:
  * Apply this patch.
  * Go to OPAC main, you should see multiple news items by default.
	* If you do not see any, go to Staff interface and add a few.
  * Each nees item heading should be clickable.
  * When clicked only that item should be shown.
	* When 'news_id' is present, only a single news item should show.
	* The breadcrumb should say 'News item' after 'Home'.

Updates:
  * Renamed URL parameter and local variables with 'news_' prefix.
  * Fixed Search-And-Replace error; 'news_news_id' => 'news_id'
  * Added breadcrumb for viewing single news item.
  * Updated OPAC to use new GetNewsToDisplay parameters
