desktop: add statistics widget dummy and application state

Add a new "statistics" application state. In the statistics state
show the statistics widget and the filter in the top quadrants.
The idea is to allow filtering and doing statistics at the same
time.

Sadly, we can't use the filter-widget in different quadrants,
because Qt's ownership model is completely broken / inflexible.
It does not support a widget having different parents and
thus a widget can only belong to one QStackedWidget.

Hiding the map in the statistics view is quite hacky:
Since the view of the quadrants is not determined by the
"ApplicationState", we have to restore the original quadrant
visibility when exiting the stats mode. Therefore, set the
original visibility-state when changing application state.

The MainWindow-quadrant code really needs to be rewritten!
