Getting pedant running with rspec 3

@mcquin I was able to get pedant running locally with these changes (although the tests don't all pass yet).  It also sends the output from the pedant subcommands to the current STDOUT.
Oh, I see your comment above on adding the server to the config.

I think that creating a branch off of the branch of chef-pedant that chef uses and adding a `--server` config option would be good, and then we won't have to monkey with the config file.
