Title: Update ocl::surf_matcher sample.

The new sample adjust some parameters thus it should always be able to
calculate valid homography matrix when input is box.png and
box_in_scene.png.
Pure cpp surf and bfmatcher implementation is also added to show the user
SURF_OCL and BFMatcher_OCL's accuracy and performance.
