Can't install on windows

[nanzeng]

Environment: Anaconda3 5.0, Visual Studio 2017

There are multiple errors when install using pip install quickfix. Here are the steps to fix them:

1. setup.py:
   ext_modules=[Extension('_quickfix', glob.glob('C++/*.cpp'), libraries=['ws2_32'])]
2. C++/Utilities.h:
   replace:
   typedef int ssize_t;
   with:
   #ifdef MS_WIN64
   typedef __int64 ssize_t;
   #else
   typedef _W64 int ssize_t;
   #endif
3. copy stdafx.cpp and stdafx.h from quickfix/src/C++ to C++/
4. copy config_windows.h from quickfix/src to ../C++

Furthermore: missing test_std_unique_ptr.cpp
`#include

int main(int argc, char** argv)
{
std::unique_ptr o;
}
`
so this forces compilation to use shared_ptr which have some issues with swig generated code
