Lockscreen : Gesture Unlock (1/2)

Change-Id: Ied813a8016130d3c0a003444d04e99e1384c56e4
Add SMS Middleware layer.

Add fix so ordered broadcasts are delivered to system
apps first in the event of a tie. This works around
the issue where terrible apps steal SMS notifications
from the broadcast queue to simply prevent notifications
that could otherwise be removed by a toggle.
