Merge remote-tracking branch 'vadz/py-args'

* vadz/py-args:
  Allow using enum elements as default values for Python functions.
  Don't always use "*args" for all Python wrapper functions.
  No real changes, just make PYTHON::check_kwargs() const.
  Refactor: move makeParameterName() to common Language base class.
  Remove long line wrapping from Python parameter list generation code.
