Thiago Macieira 2376a5c4e0 Make the event notification on Windows be mandatory in all dispatchers
This way, QWinEventNotifier will work on all Windows systems, not just
with the default event dispatcher. Other dispatchers (other than
QWin32EventDispatcher) are permitted, so the class should not abort just
because of that.

If a dispatcher really doesn't want to implement this, they need to
implement the virtuals to do nothing, possibly print a warning.
