process server opening HS
https://github.com/oberstet/AutobahnAndroid/blob/master/Autobahn/src/de/tavendo/autobahn/WebSocketReader.java#L516
this should be addressed as part of https://github.com/crossbario/autobahn-android/issues/92
With current master, the relevant FIXME is here: https://github.com/crossbario/autobahn-java/blob/master/autobahn/src/main/java/io/crossbar/autobahn/WebSocketReader.java#L535
https://github.com/crossbario/autobahn-java/pull/277/commits/31f63a1b2eab805c6398816d5bafbea64974d431 brings us one step closer to implementing this. Now I only need to read a bit into the WebSocket rfc :-)
