title: Don't include jquery in a Rails app using ember-cli with ember-cli-rails
body: <p>I have an existing Rails app that I'm adding an ember-cli app to using the ember-cli-rails gem. The Rails app already includes jquery and jquery-ui via the Rails asset pipeline and the jquery-rails gem.</p>
  
  <p>Ember-cli also includes a different version of jquery which when loaded doesn't have the previously included jquery-ui components loaded.</p>
  
  <p>I want to disable the Ember-cli jquery and just use the one already included.</p>
