SystemUI: Silence verbose NetworkController logging

Change-Id: I2f9ef2804b83d31fe6745e1db4ed9b905d83cb56
Frameworks: Gesture Lockscreen (1/2)

This adds the ability to us a hand drawn gesture as
a means to unlock the device.

In the case that the gesture is forgotton or not
being recognized correctly, the fallback will be the
same as when using patterns.
