kdeui: implement save for KNotificationConfigWidget

another rewrite of bits dating back to 1997 done:
https://ibb.co/5GKtQT1

while working on it the idea of writing custom widget that will act as
checkbox but look something like a slider and using that instead of tables
popped up (the widget design itself is not new but using the widget in new
UIs will be).
