    SystemUI: double tap to sleep improvements

    * Make it more reliable
    * Add it to keyguard
    * Add a content observer to not always query Settings.System on every
    touch event

    SystemUI: Use Tuner API for CM settings

    Get rid of all the excess code by implementing TunerService.Tunable
    and observing any changes made to the settings through it.

    Remove UserContentObserver as the Tuner API handles user switches.

    Also remove some unused imports that were introduced in earlier
    CM commits, but were never removed since.
