upgraded to FLANN 1.6. Added miniflann interface, which is now used in the rest of OpenCV. Added Python bindings for FLANN.

make type registration ordering in cv2.so consistent with the declaration order (fixes the class hierarchy; see ticket #1113)

- static class member modifier processing is fixed (moved from 'rettype' to 'func_modlist')

moved Python bindings source code into src subdirectory; preparing to add python/doc and python/test subdirectories

fixed the ordering of parameters in PyArg_ParseTupleAndKeywords, added correct Ptr<CvDTreeSplit>::delete_obj() (ticket #406)

extended Python bindings; not merged into cv.cpp yet; and many of the helper functions, like pyopencv_to_*, pyopencv_from_* etc. are still missing
