QML WebSocket Type - method receiveBinaryMessage documentation

Hi,
There's an error that sliped into the documentation of the QML WebSocket Type of the newly implemented receiveBinaryMessage() signal.

The documentation states that the signal's argument is a QString, when in fact it's an ArrayBuffer - as described for the sendBinaryMessage() method.

The error can be found in the patch that implements these functionalities :
https://github.com/qt/qtwebsockets/commit/9b804c270d11d34d37c08a5145dba083a6b0c1a7#diff-972828f3f4fa4303180be85da2f35d7aR94

Documentation page :
http://doc-snapshots.qt.io/qt5-5.8/qml-qtwebsockets-websocket.html#sendBinaryMessage-method

This affects the documentation and the helpers in QtCreator - which expect a string.

PS: it would certainly be interesting to give some example(s) of how to handle this binary data in QML. I myself haven't yet figured out how to use an image received that way.
