Works but kinda hacked toogether using the treeview example in the qt
docs.
The friendsmodel now works but there are still some work to be done.

*Move sorting out of the model. It sorts online/offline atm which does
not work because it uses statushelper for translateing the status to a
more managable format so the friends are are always in the offline
secition.

*Make better data change notification for the view. Right now its
somewhat "manual". I think the correct way would be to implement the
data/setdata and insert/move/remove-row methods.
Forgot the project file.
