Added spherical and cylindrical warpers, which work in the portrait mode -- when poles are located NOT at (0, -1, 0) and (0, 1, 0) points, BUT at (1, 0, 0) and (-1, 0, 0) points.

removed void integral(const GpuMat& src, GpuMat& sum, GpuMat& sqsum, Stream& stream) - it fails with NPP_NOT_IMPLEMENTED error
updated docs, accuracy and performance tests

More granular build of Java API: it is now possible to build Java wrappers only for the subset of OpenCV modules
