#102 ommit first parameter self in object methods

[Christof Boeckler]

For a class's user the first parameter of a method is implicitly set by Python so it is actually not part of the user visible interface and followingly should not be documented as such. (Althoug no real Pythoneer cares about that, for entry level teaching this could be an important issue.) So please at least add an option --no-self to ommit all self occurances (no matter what they are called :-)
