Title: Update README.md

When deploying a Rails 4.1 app it would fail on any `rake` task, unless I used the `bundle exec` command.

This meant that Pushion Passenger tried to start the server it gave me the error: `uninitialized constant ActionDispatch::XmlParamsParser`

Adding the require fixed the issue.
