    knotty: show task progress bar
    
    In addition to the "currently running n tasks (x of y)" message, show a
    progress bar for another view on how much of the build is left. We have
    to take care to reset it when moving from the scenequeue to the
    runqueue, and explicitly don't include an ETA since not all tasks take
    equal time and thus it isn't possible to estimate the time remaining
    with the information available.
