…or larger distances.

The symptom is currently losing face tracking at distance of approx 2 meters.
the additional margin of 0.1 * width and 0.1 * height is only effective for short ranges (e.g. less than 1 meters) since the face is relatively large.
For distances up to 2 meters, need additional margins approx 0.2 x width and 0.2 x height since the face is smaller
For distances up to 3 meters , need additional margins approx 0.3 x width and 0.3 x height.
For distances up to 4 meters, need additional margins approx 0.4 x width and 0.4 x height.

Currently CameraFactory::getCameras only enumerates 1 PS3 eye camera and up to 4 OCV cameras.
Should be able to enumerated multiple PS3 eye cameras

This reverts commit 943aeae.

 Need to increase the boundary for face detection by 10% to compensate for increased size due to yaw, pitch and roll
 But we also need a minimum amount of pixels for detection at farther distances where the face is smaller
