    status/bluetooth: Indicate progress on toggle
    
    Turning bluetooth on or off can be very slow ­– 10-15 seconds on
    my system – and we currently don't provide any feedback that
    something is indeed happening until the state changes at last.
    
    Address this by using the `acquiring` icon when the adapter is
    in a transitioning state.
