Felix Walter 594eca6c8d Apply first suggestions from !126 
- remove comments on "callback-style" serialization (not needed)
- define magic number in Python AAP 2.0 client via descriptive var
- make `secret` in Python AAP 2.0 client a private variable (used
  nowhere else and should not be a class property)
- add missing Python docstrings
- add some comments explaining behavior
- language enhancements and fixes in docs and comments
