Operating on forked pull requests is dangerous if it's a public repo
because anyone can make a pull request to a public repo. We default to
false like CircleCI and TravisCI who don't allow credentials to be
available on fork PRs.
- Refactor EventParser so it returns a comment we can send to the pull
request when a bad command or help command is commented.
- Remove now unneeded HelpExecutor because we comment right from the
EventsController now
- Use pflag package to parse commands instead of doing it manually
- Comment back when user types terraform instead of atlantis
