ChaosLab: Add annotation to be used when adding new features to the lab.

This should be used when adding completely new features to ChameleonOS,
and not for simple things that expand upon a current feature.

Gesture Anywhere: Add gesture anywhere feature into the ChaOS Lab [1/2]

When enabled a user can activate the gesture anywhere view by touching
the designated trigger area.  If a gesture is recognized as one the user
has created and assigned to an action, that action will be performed.
Since this is part of the system UI and implemented as an overlay, it
will be available and usable system wide, with the exception of the
keyguard for obvious reasons.
