Cleanup: Make WindowsTitleUpdate a global object

Browse source 
WindowsTitleUpdate is such a trivial object (a QObject with a single
signal and no own state), that it's not really understandable why
it would need all that "singleton" boiler-plate. Just make it
a default constructed/destructed global object.
