* the first commit in the merged dnn: convert some public API from Blob's to Mat's
* temporarily or permantently removed OpenCL optimizations, which are not always stable nor usually very efficient; we'll likely use Halide instead
* got rid of Blob and BlobShape completely; use cv::Mat and std::vector<int> instead
* fixed a few compile errors
* got rid of separate .hpp files with layer declarations; instead, put everything into the respective .cpp files
* normalized all the layers' constructors; we concentrate on loading deep networks layers from files instead of constructing them from scratch, so we retained only SomeLayer::SomeLayer(const LayerParams& params); constructors
* fixed sample compilation
* suppress doxygen warnings
* trying to fix python bindings generation for DNN module
* temporarily disable python bindings while we refactor the module
* fix win32/win64 compile errors; remove trailing whitespaces
* fix win32/win64 compile errors; remove trailing whitespaces
