Title: Don't mask TwythonStreamer exceptions

Exceptions in handlers or on_success which subclass ValueError would previously be caught and reported as a JSON decoding problem, and on_error() would be called (with status_code=200).

Note that, unrelated to this, you might want to catch handlers errors somehow, since it would certainly interrupt streaming.
