Fix MinGW build, #505

<intrin.h>, included by SDL_cpuinfo.h via SDL.h, defines strcmp.
If the idlib/Str.h `#define strcmp idStr::Cmp` hack is visible when
that file is parsed, there's a compiler error (because strcmp in
intrin.h is replaced with idStr::Cmp then).
So I reorderedd includes a bit until it compiled again..
