Swipe between Notifications & Quick Settings

Swipe Notification bar to switch between Notifications & Quick Settings. Tested with v20.1.0 working beautifully! 

Tested with both the System theme which shows the notification bar at the base of the notification/quick settings pull down, and with my paid Lozone theme which does not actually show the notification bar but has the themed base with an arrow. Worked perfectly with System and Lozone theme.
