Migrate From react-rails

If you are using react-rails in your project, it is pretty simple to migrate to react_on_rails.

• Remove the 'react-rails' gem from your Gemfile.

• Remove the generated lines for react-rails in your application.js file.

//= require react
//= require react_ujs
//= require components

• Follow our getting started guide: https://github.com/shakacode/react_on_rails#getting-started.

Note: If you have components from react-rails you want to use, then you will need to port them into react_on_rails which uses webpack instead of the asset pipeline.
