QuietHours: Change Logic (2/2)

Makes sense to me that turning QuietHours
    on should TURN QUIET HOURS ON with
    default time constraints applied.
I.E. QuietHours between 12:00am && 12:00am
    means QuietHours all day.  Having to
    adjust end time to 11:59 is redundant
    and not exactly the clearest implementation.
    Especially when we have a QuickToggle that
    directly toggles the setting on/off.

PS2: Vibrations as well.

Kill floating activities running in the same thread when tapping outside
This change makes all activities from the same app to be finished when we tap outside the halo window. Other apps running in different threads
(floating or not) won't be finished.
