Andreas Kling 5e19e72a6a LibGUI: Simplify RadioButton by using AbstractButton exclusive mode
Making an AbstractButton exclusive means that we enforce that only one
of the exclusive buttons within the same parent widget can be checked
at a time.

RadioButton was doing exactly the same thing, except in a custom way.
So just remove the custom code and make it exclusive. :^)
