AppVeyor for the CLI?

[lassik]

You seem to be doing a Windows build of core in AppVeyor, which is great. Would it be possible to set up a Windows build of the CLI too? I was gearing up to send a PR for safer file replace as discussed earlier and that would work differently on Windows due to differences between the Windows and Unix file system APIs.

Great idea! Definitely want more official Windows support 🎉 .

Started PR #95 about it. Since we've just been wrestling with CI a lot, let's try to get this one in too :)
