Fix for the v110_xp toolset in vs2012. Removed winuser.h from afxresmw.h, nothing seems to be using it, but it breaks something in string.h. I did not change the projects to use v110_xp by default, to get an xp compatible binary, you have to call it from command line like this: msbuild pcsx2_suite_2012.sln /t:Build "/p:Configuration=Release AVX2" /p:PlatformToolset=v110_xp /m. Change Configuration=... as needed.
