Fixed compile error under VS2015 /c++:latest, caused by using random_shuffle

Browse Source 
Now if we detect C++11 compiler, or MSVC in version corresponding to VS2015,
we switch from using `std::random_shuffle` to `std::shuffle`.

`std::random_shuffle` was officially deprecated in C++14, and removed in C++17.

Also removed guarded inclusion of `<random>` header, as there was nothing
in the header that used it.
