How to handle super calls in trait code

[PragTob]

• when we include a method and its corresponding super methods: rename super method _superClassNameMethodName and change call in method
• when we only include a super method, but no overwriting subclass method: change super calls to that method to self calls to that method in the included trait code

[lauritzthamsen]

we don't include super-called methods from superclasses by default and we only change super calls when we call a super method that is actually included into the target class.
