a big patch; use special proxy types (Input/OutputArray, Input/OutputArrayOfArrays) for passing in vectors, matrices etc.

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

added hconcat & vconcat functions for joining matrices; moved some inline functions out of the headers; fixed several bugs in documentation; removed MatND from docs

fixed several GCC warnings; fixed crash in kmeans test (because of cv::swap(Mat&a, Mat&b)) (ticket #616)

added more helper macros to the function declarations, to assist the Python wrapper generator. Fixed memleak in Mat::operator()(Range,Range) and the related functions (Mat::row, Mat::col etc.)

fixed bug with Mat::dataend initialization. Now morph-ex test passes; Also fixed CV_Assert() implementation

added Mat::push_back, pop_back and related operations; enabled reading/writing/creating/copying matrices with zero dimensions.

fixed Mat::Mat(const IplImage*, bool) constructor (ticket #487). fixed the bayer demosaicing part in the new cv::cvtColor implementation

updated 3rd party libs: CLapack 3.1.1.1 => 3.2.1, zlib 1.2.3 => 1.2.5, libpng 1.2.x => 1.4.3, libtiff 3.7.x => 3.9.4. fixed many 64-bit related VS2010 warnings
