Title: Optimized version of BackgroundSubtractorGMG

This is an optimized version of BackgroundSubtractorGMG algorithm (10-15x faster than previous). It uses cv::Mat instead of std::vector and std::list, that saves time on memory allocation. Also new version use tbb. Results from new version may a bit differ from old version on object's boundaries.
