As discussed at <a
village pump</a>, it would be nice if it was possible to only show anonymous
created pages at special:newpages.
When the patrol feature was turned on it was also irritating that it wasn't
possible to insert text at the top of special:newpages for explanation.
The attached patch does
*Make it possible specify hideliu, hidebots, hidepatrolled as URL parameters,
and via an interface at special:newpages.
*Insert a short text at top of special:newpages.
