Statusbar: dont refresh the signal cluster during panel bar interaction

The signal cluster constantly refreshes below the notification panel.  Lets
return before the updates are processed if we're interacting with the panel bar
to help preserve framerates

PS2: allow updating the quicksetting tiles with a network controller attached
PS3: don't tick notifications

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.
