@Tofee Shouldn't we update the OrientationHelper.qml as well?

import QtQuick 2.9
import QtSensors 5.11

[Tofee]

I'd prefer doing that for the whole project; most of our QML imports are quite outdated.

OK we'll keep that for later. I understood from some comment on SFOS that we might be able to do without versioning altogether?sailfishos/fingerterm#6
