v0.11.1

• New feature: you can control what's happening with the websocket connections at the end of the test: leave open (default), close on websocket level or close on tcp level, by setting JMeter property websocket.thread.stop.policy.
• Fix: all result viewers will now correctly show the size of received bytes. Frame payload is counted as 'body', frame headers as 'headers'.
• By default, filtered frames do not contribute to 'received size', but this can be changed by setting JMeter property websocket.result.size_includes_filtered_frames
• minor bug fixes and documentation improvements
