title: CKEditor image width and height as HTML attribute in stead of inline styling
body: <p>I´m making an email program website which allows you to upload images. You can resize the image but it will be written as inline styling: <code>style="width: X; heigth: X"</code>.</p>
  
  <p>When you want to preview your email inside outlook the image will be shown with full width and height.</p>
  
  <p>So instead of </p>
  
  <pre><code>&lt;img src="x" style="width: x; heigth: x";&gt;
  </code></pre>
  
  <p>I want</p>
  
  <pre><code>&lt;img src="x" width="x" heigth="x"&gt;
  </code></pre>
  
  <p>I'm currently using the latest version of CKEditor: V4.7.3</p>
