archwiki: Implement short URLs
The wiki people has been wanting this for some time, so let's implement it. This change the url from: https://wiki.archlinux.org/index.php/Main_page to: https://wiki.archlinux.org/title/Main_page  https://wiki.archlinux.org/index.php?title=ArchWiki_talk:Requests&oldid=648459#index.php_in_url_address
Draft as I need a final ack from the wiki people, that
/title/<page> is what they want.
Also I need some help deploying this as there is a chance I missed something.
