Feature Request: config file and init function

[digitalfiz]

It would be awesome if we could do something like butler init and it ask questions like what username, game and channel then puts them in a butler.json file that can automatically be read when simply doing things like butler push or butler status.

Those things should probably be overridable too incase you wanna push a different channel for whatever reason.

I would really love for butler to remain config-less, to respect the principle of least surprise.

I think pushing the same thing often is largely covered by existing build systems :)
