Progress on the Gilectomy

The silliness is that, for Python 2.7 at least, it uses the 2008 toolchain, but uses 2013 or so project files, so you can't just get one Visual Studio and have it work. I haven't had to build Python 3 on Windows yet, but it'd be much better if Python moved to a build generator like CMake (patches exist to do so) or the like. Meson, waf, and scons get you in a bootstrapping problem, but they'd work too otherwise.
