Motivation: Unfortunately as a result of apple#108 the WebSocketFrameDecoder can emit a WebSocketFrame more than once if the user closes the connection in channelRead, or any other callback while decode() is on the call stack. This is obviously less than ideal, as it can allow multiple delivery of frames. Modifications: Given WebSocketFrameDecoder a no-op implementation of decodeLast. Result: No multi-delivery of frames.
