title: Broccoli/Ember-cli: if I'm importing a css file why do I need jquery?
body: <p>I'm trying to import a css package and when I run Broccoli (using <code>ember server</code>) it's complaining I need jQuery:</p>
  
  <pre><code>app.import('bower_components/materialize/dist/materialize.css');
  </code></pre>
  
  <p>Error message:</p>
  
  <pre><code>Missing bower packages: 
  Package: jquery
    * Specified: ^1.11.1
    * Installed: 2.1.4
  </code></pre>
  
  <p>Note: I'm not planning on using the jQuery components, just the css...can't I just import that without throwing an error?</p>
