Turn off the hound

It wasn't respecting my .rubocop.yml configuration file, so it was
leaving unhelpful comments. I already turned it off on the website, so
now I'm removing this artifact of those days.

I'm leaving the rubocop config, and I'm still having it auto-run on
Travis, so consistent style will still be enforced. People will just
have to figure out why their builds are failing.
