Use filecmp to compare files. Fixed up some comments
KeybaseAdmin.login() implemented. Refactored JSON gets/posts
Forgot to add scrypt to requirements.txt
Learned about tox and verified commit passes as expected

I'm not sold on this change, though. Because get_json_from_url(url, payload, method = 'get') is no longer a requests object, we can't do resp.url or resp.txt. This means the error messages are significantly less useful.

Not quite sure what to do here. I'll circle back around and see how I might get these back.
