Adding autopatrolled user group for dewikivoyage

In this change, an autopatrolled group for de.wikivoyage
with the user right 'autopatrol' was created.
Users can now be added/removed to that group by sysops
and all users with 200 or more edits get automatically
added to that group once they edit the wiki.
