Well, because normally this is done by changing the ::key()'s to affect the
sorting. Much easier and faster because takeItem/insertItem does some
bookkeeping which makes it slow. 

I don't see the reason why we must extend QListView with methods that are
just slow. A general rule is only implement those things that can be done
efficiently in an API.
