[Development] QSettings refactor updates

[private at bernhard-lindner.de]

I once programmed a class hierarchy targeting the same features (and  
much more). It consited of settings group objects and settings object  
ordered in a tree hierarchy. That hierarchy was much more complex  
(having templated settings, units, limits, flags, value checking,  
attributes for GUI form generation etc.). Each of the groups and  
settings shared a common interface base.

One feature that was very useful was the fact that we could  
display/edit the settings hierarchy using a QAbstractItemModel in a  
QTreeView.

Do you intend to support the latter with your classes?
