Made it work when compiled using CLANG on Windows.

I have managed to make it work when compiled using CLANG on Windows. When compiled using Visual Studio, it still runs into Stack Overflow. I have also refactored the code a bit. I think the parser is quite a bit faster now, but I haven't done precise measurements. To download executable files for various operating systems, once again, see the release v1.5, the functionality has not changed enough for me to bother to make new executable files.
