Possibility to inject stream options into constructor of websocket client
Fixed bug when no (null) stream options are supplied
Removed send (WebSocketTransportInterface, already inherited from TransportInterface) and getData (WebSocketMessageInterface, already inherited from MessageInterface)
In older PHP 5.3.* versions, there was a bug (https://bugs.php.net/bug.php?id=43200) which threw a fatal error, if an abstract method/interface method was defined again abstract. I think this was the case prior to PHP version 5.3.9.
