Subject: [PATCH] make control a cooperative object

I used the observer pattern to propagate changes in a usercontrol object. For that purpose my widget derives from UserControl and another class. Calling super().__init__() in my class did not work because I had the wrong order in the class calls, i.e., class MyWidget(UserControl, Subject), rather than class MyWidget(Subject, UserControl). By including super().__init__() in the Control class such points of confusion are easy to prevent. Here is a further discussion:
