Subject: [PATCH] Keyguard: Lock icon improvements

There was a ~300ms delay (I think) between the actual dismissal of the lock icon from keyguard locked to unlocked (only with no security method activated).
So, mKeyguardIndicationController.setVisible(false) has been moved to KeyguardgoingAway() to anticipate the icon dismissal with a small setAlpha hack in KeyguardIndicationController.
