QOrbitCameraController wrong behaviour

The QCamera class allows to define the vertical orientation with upVector. But the orbit camera controller ignores it and uses axis Y as vertical.

The reason is in the method QOrbitCameraController::moveCamera() contains a line:

    const QVector3D upVector(0.0f, 1.0f, 0.0f);

which (i guess) should be changed to:

    const QVector3D upVector = theCamera.upVector();
