Download a platform-specific GPG archive on installation

[smashwilson]

A regular npm install should drop an atom/squeegpg-native archive for the current platform within this directory.

Lightly "inspired" by @shiftkey's dugite work.

Does this make desktop/dugite-native#36 less urgent now?

[smashwilson]

I hope so! My goal here is to get something we can share between atom/github and Desktop for GPG integration. The TypeScript half of things has been started, too.

Mind if I ping you for feedback on a PR when I get to the point where I'm hashing out the public API, to make sure it's something we can both use? It'll likely be a little more complicated than the GitProcess one because we have the GPG homedir and gpg-agent process to manage as well.

Oh, also, to address some of my concerns on that issue, apparently Git for Windows already bundles gpg 1.x. So...

Sure thing. I haven't really thought about our use case desktop/desktop#78 much lately but this gives me time to catch up.

It does? Rad, I'll confirm that it's also in MinGit and update that issue...

👍 No rush - I know this isn't on your roadmap any time soon. Mostly I want to make sure (a) you're vaguely aware I'm doing this and (b) I don't box myself into an Atom-shaped corner somehow.

Also, there's certainly a gpg binary in my git install that I don't recall putting there myself:

We should probably still check with legal, at least about licensing issues?

That's the full version of Git for Windows - MinGit has a bunch of tools removed that aren't important when embedding Git into apps, and here's what we ship in dugite currently:
