title: CKEditor in chrome extension
body: <p>I'm trying to instantiate CKEditor in chrome extension but I get the following error:</p>
  
  <blockquote>
    <p>Uncaught TypeError: Cannot read property 'tools' of undefined</p>
  </blockquote>
  
  <p>with the object being undefined is <code>window.parent.CKEDITOR</code>.</p>
  
  <p>Here's some block of my manifest file where I imported only some of the files of the ckeditor folder:</p>
  
  <pre><code>"content_scripts": [
    "css": [
       "bower_components/ckeditor/skins/moono/editor.css"
     ],
     "js": [
       "bower_components/ckeditor/ckeditor.js",
        "bower_components/ckeditor/styles.js",
        "bower_components/ckeditor/lang/en.js"
     ]
  ]
  </code></pre>
  
  <p>And here's how I instantiate the editor:</p>
  
  <pre><code>var options = {
    language: 'en',
    customConfig: '',   //no default config loaded
    toolbar: [
    [ 'Format', 'Bold', 'Italic', 'Underline' ,
      'BulletedList', 'NumberedList', 'Outdent', 'Indent', 'Link']
    ],
    enterMode: CKEDITOR.ENTER_DIV,
    on: {
      instanceReady: function() { console.log('ready'); }
    },
    removePlugins: 'elementspath'
  }
  
  var instance = CKEDITOR.replace('textarea1', options);
  editor =  CKEDITOR.instances[instance.name];
  </code></pre>
  
  <p>Anyone has managed to use CKEDITOR on a chrome extension and wants to share some hint? 
  Thanks</p>
