    GlobalActions: Fix setting ringer mode in global actions

    It looks like we did not bring in this full feature for cm-13.0.
    This patch updates SilentModeTriStateAction to match cm-12.1 with
    one minor change.  We can no longer set the zen mode by writing to
    Global settings directly.  The ZenModeHelper class actually checks
    when a change is made and resets it.  The fix is to use
    INotificationManager.setZenMode() instead.

    Fix GlobalActions sound panel iconography.

    The priority and none icons were using old zen icons and did not
    match up with the status bar iconography. We are now in sync. Also
    aligning the prefix to match the other icons present in this dialog.
    Lastly, creating new drawables for the two sound options so that
    we don't clash designs with the Settings view, which also used the
    same icons.

    GlobalActions: Always use setZenMode

    When set to silent mode, the user cannot change the ringer mode to
    vibrate or ring.  Notification manager listens for changes to the
    zen mode setting and will switch it back if there is a mismatch.
    Using INotificationManager.setZenMode takes care of changing the mode
    and keeping track of the updated change.
