title: CKEDITOR how to add span to every line
body: <p>I use ckeditor and I would like to wrap every line with span tag.
  For example, when I enter text in the editor I get:</p>
  
  <pre><code>this is the first line
  &lt;br&gt;
  this is the second line of text
  &lt;br&gt;
  and the third one
  </code></pre>
  
  <p>I want it to be by default:</p>
  
  <pre><code>&lt;span style="font-size:12px;"&gt;this is the first line&lt;/span&gt;
  &lt;br&gt;
  &lt;span style="font-size:12px;"&gt;this is the second line of text&lt;/span&gt;
  &lt;br&gt;
  &lt;span style="font-size:12px;"&gt;and the third one&lt;/span&gt;
  </code></pre>
  
  <p>I know there is something called "dataProcessor" but I don't understand how to use it.
  If it is possible to add this rule also to pasted text it will be even better.</p>
  
  <p>Thanks!</p>
