- cvAddButton done
 - All the "actions" of the toolbar are working
 - Window properties done

do not use WIN64/_WIN64 anymore - CMake did not set it anyway. Use WIN32 + __x86_64 or _M_X64 instead. Also, make VideoInput optional (WITH_VIDEOINPUT=ON/OFF) => now Mingw-dw2 can build OpenCV

fixed the singular case in the rodrigues test. increased the error threshold in findFundamentalMat test

 - fixed icvFindTrackbar bug

fixed VS preprocessor condition to include pmmintrin.h (which is available in VS2008 and later versions, but not in VS2005)

added workaround for strange tmpnam() output from VS2010. turned off optimization for DCT & DFT on Win64 for VS200x (VS2010 builds it fine)

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

 - Finished toolbar: the last icon opens an external window with the trackbars inside

 - Add icons for toolbar in new folder (files_Qt) (later, will delete useless icons)

 - Add toolbar
 - Clean the code
 - Window properties in progress

Simple implementation of StereoBM_GPU.
It is excluded from compilation now.
