Hound/Rubocop Config

[joe-sharp]

Any chance you can check-in the Rubocop config? The rules that Hound enforces are a bit difficult to predict. If Hound is using its own default config may I suggest going with something closer to what Rubocop uses for defaults? Happy to update the codebase to adhere to the rules as well. Thanks for considering it!

It comes from our guides repo.

I'd like to switch over to standard, which is what we've done everywhere else at some point.
