[dev] removeUserData permissions

[Karsten Fourmont]

Hi,

in Turba, Nag, Mnemo and Kronolith we now have a removeUserData function 
in the external api. This deletes all data (like private address book 
and history) of a user for the respective app.
removeUserData is automatically called for each app by Auth::removeUser 
when a user is removed.

However this doesn't work as expected due to permission issues:

when a user (let's call him "admin") removes a user "jondoe", "admin" 
normally doesn't have write (delete) permission on "jondoe"s private 
data. So the _delete and _list functions internally used by 
removeUserData return "permission denied".

Any ideas how to fix this?

cheers,
  Karsten
