    core, add loading overlay and activate it while loading activities · 30afb581

    The loading overlay is meant to signal heavy work to the user, and
    should be used whenever the ui feels like  frozen. Therefore it
    deactivates all ui-interaction (except key-handling).
    
    There should be only one instance of Loading in the whole application,
    which is a sibling of the stack-view. Therefore we pass it into the
    activities via the ActivityBase.loading property, as we do e.g. with
    audioEffects.
    
    For now we activate it always during activity loading through the
    activity-loader. Especially on (slower) Android devices the intial
    rendering of the activity-scene takes some time, and so far looked
    like a freezing ui to the user.
    
    We might want to activate the loading overlay only on mobile devices,
    as a desktop should render its scene pretty fast.
