Add icons of selected desktop to Desktop TabBox

Browse source 
To support this feature the DesktopModel is turned into a tree model with
the desktops on the root level and the Client's at the next level.

In the view a VisualDataModel is used which kind of supports a tree model
by setting the root index. A list view is added underneath all the
desktops showing the icons of the windows on the desktop one switches to.
