Removed _stringio from Windows build.

For some yet unknown reason, MSVC's linker fails to resolve
_stringio's module initializer (PyInit__stringio). This probably means
the module is not build correctly. Therefore, I am removing Windows
support temporarily until I find how to add new modules properly for
MSVC.
