Fix some Windows issues

1. We need to set a Windows target to get rid of warnings when compiling
   files that include windows.h
2. By default Boost will try to automatically link against boost_system.
   In order to prevent this, we define BOOST_ALL_NO_LIB
3. Somehow, I had to include winioctl.h in Platform.cpp. According to
   the documentation from MS, this shouldn't be necessary as windows.h
   includes this as well. However, for me it didn't compile otherwise.
