Re: Update Windows binaries

I'm having trouble getting pywin32 installed in MSYS2.  When I try to install with pip, I get errors

$ python3 -m pip install pypiwin32==219

    Complete output from command python setup.py egg_info:

Collecting pywin32>=223 (from pypiwin32==223)

  Could not find a version that satisfies the requirement pywin32>=223 (from pypiwin32==223) (from versions: )

No matching distribution found for pywin32>=223 (from pypiwin32==223)

Downloading and installing outside pip isn't an option because distutils doesn't support silent installs (https://github.com/mhammond/pywin32/issues/845).  If you run the command locally, you can see it pops up the GUI installer.

$ wget --no-verbose --output-document=pywin32.exe https://github.com/mhammond/pywin32/releases/download/b223/pywin32-223.win-amd64-py3.6.exe && ./pywin32.exe && rm pywin32.exe

We could try compiling pywin32 from source, but it looks like it might be complicated.

When I do python --version, I get "Python 3.6.2" (and that's the version I see pacman downloaded).  I think maybe the AIO installer is installing some stuff I don't have in pacman yet.

Probably not super-helpful, but I notice that you're just using
`python` there, which seems to be defaulting to Python 2.7, whereas we
definitely want 3.x for current Meld.

Either way, I'm really happy for others to be looking at this.
