Vlad Zahorodnii d73610d6d6 scripting: Introduce VirtualDesktopModel
This can be useful for QML scripts that deal with virtual desktops.

The virtual desktop model keeps a copy of virtual desktop objects to
avoid hitting asserts in QAbstractItemModel (it has some asserts to
ensure that indices passed to beginInsertRows() or beginRemoveRows()
make sense).
