Fordragon16, failed attempt to implement playEvents via python (#195)

* changes in __init__.py prevent Dragon 16 from halting by an ESP error.
* try the playEvents fix of Dane in __init__.py
* remove dependencies for natlink (put them in natlinkcore if necessary)
* failed attempt to implement playEvents with python.
