BackLinks: Purge all empty unreferenced pages

The contents of all pages are searched to find links to the current page. The BackLinks function also answers the question: "Which pages contain the title of this page?".

To display the list of pages which all contain multiple links use a pagelist as page argument. For example

  <?plugin BackLinks page=Milk,Honey ?>

would display all pages which contain links to Milk AND Honey.
