FW: Active Display from ChameleonOS SQUASHED (1/2)

Add active display to ChameleonOS [1/2]

    This is the ChameleonOS implementation of the active
    display feature, similar to that found on the Moto X.

    When enabled the screen will turn on and display the
    incoming notification.  The user can then open the app
    for the notification, dismiss the notification or unlock
    their device normally.

    Additional notifications, if any exist, will be displayed
    below the ring notification and can be viewed by touching
    the notification icon.  The user can simply slide their
    finger across these other notification to quickly view
    them.  The last one touched will remain in the ring and
    the user can then perform any of the actions listed above.

    PS2-PS12:
    All the changes that brought us to this current implementation.

Delay hiding systemui by 100ms
    When disabling the keyguard, the systemui visibility is
    changed and can occur after we hide it so delaying this
    a bit resolves that issue.
