lot's of changes; nonfree & photo modules added; SIFT & SURF -> nonfree module; Inpainting -> photo; refactored features2d (ORB is still failing tests), optimized brute-force matcher and made it non-template.

HAVE_CONFIG_H -> HAVE_CVCONFIG_H

reworked nearly all of the OpenCV tests (except for opencv_gpu tests) - they now use the Google Test engine.

added tests for some detectors; made features2d object create functions as static classes methods; fixed OpponentColorDescriptorExtractor, BriefDescriptorExtractor (on rgb); renamed DynamicDetector

modified features2d interface; added algorithmic test for DescriptorMatcher; added sample on matching to many images

fixed FernDescriptorMatch; optimized keypoint regions matching in detector/descriptor evaluation; added CalonderDescriptorExtractor to evaluation tests

renamed createDetector to createFeatureDetector

replaced detector/descriptor evaluation functions from test to features2d; modified VectorDescriptorMatch constructor; removed commented calonder descriptor implementation

Changed VectorDescriptorMatch interface to add factory capabilities and changed factory functions interface (return smart pointer)
