Due to a suggestion (forgot from whom, though...) the Tasks extension
can now automatically create a task for a newly created article. This
can be configured separately for article creations by logged-in users
and anons (should we allow that again).
Major advantages of this mechanism over the "new pages patrol" are
* tasks are not forgotten, even if noone checked the page for days or
* tasks can be closed by logged-in users, so patrols can focus on
unchecked (new) articles
P.S.: Thanks to Brion and Hashar for fixes and improvements!
