Fix compilation with (all versions of) MinGW

Browse Source 
Commit 320b16110f0f9cef032a64846dc792d40ccd367b changed the arguments
of swprintf to be compliant with latest MinGW-w64 headers: The headers now
excludes the non-standard swprintf(wchar*t,wchar_t*,...) version for C++11.

However, the swprintf(wchar_t*,size_t,wchar_t*,...) version is actually
not supported by e.g. stock Mingw-32 from mingw.org.

Instead, use _snwprintf(wchar_t*,size_t,wchar_t*,...), which both
MSVC, and all MinGW versions should support.
