the above list of functions are leftovers from the GTK version where
we wrote ourselves OS native code to handle the settings writing.
now we can use Qt for that, but the functions still make sense, in a way.

what Dirk describes, i believe, is a local class or a set of global
C++ functions that will wrap the QSettings integration in Subsurface.
this would be nice, because we can have better control over things and
don't need to use the QSettings class directly inside the code.
