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.

Since the QML port the LayoutMode had been hardcoded to vertical
layout making it a completely useless code-path.
MinWidth/Height are nowadays completely controlled by the QML
theme. They were not read anywhere except in the kcm, but there
not even bound to a ui element.
The selectedItemLayoutName is also not used anymore with the
new themes.
