New 'blog-like news system.
Should make it easier to keep up with news updates!
Since:
  1. Doesn't require editing news.html in the CVS tree and
     recopying it/reinstalling just to add a news item.
  2. Doesn't involve editing menu.php3,
     since the modified date and "new" icon is automatic now.
  3. Looks nicer.

Also, it is based off the db, so other sites can have other news,
which they can maintain independently.

There are of course, neat features that have been suggested that
could go with this, such as message updates and automatic
mailing list mailings of news, but those don't exist yet...
