Title: New: KLT Tracking

Add a pyramidal KLT tracking and an application openni_klt that tracks detected Tomasi points from RGB-D sensor and tracks them.
Detection is done 1 per 30 acquired cloud so detected points are tracked for 29 frames and the new keypoints are given to the tracker.
It will serve as a comparison basis for the upcoming RGB-D version.
