Fixing alarm clock bug

The alarm clock doesn't actually hide the view until AFTER Facelock starts
hence the need to kill Facelock after it has started when the even is caught
Also fixing phone black box background in case the user cancels the call quickly

Also eliminating blackscreen after 4s for multiple reasons
so people can login if lockscreen locks up
also so cancel fade is to the backup lock
