eye + face annotation (menpo + landmarkio-server)

[headupinclouds]

Add eye model annotations to face landmark dataset with sufficient resolution for eye models: iris (ellipse) + pupil (ellipse) + eyelid contours (16 points) + eye cream (9 points).

Will be adding simple opencv highgui tool for local eye model annotation.

Consider adding functionality to: https://github.com/menpo/landmarkerio-server
