title: GXT 3 ContentPanel autoheight or FillLayout
body: <p>I can't get ContentPanel to take all the available height inside BorderLayoutContainer.</p>
  
  <p>In version 2.x it was as simple, as <code>setLayout(new FillLayout());</code>, but it is no longer valid for GXT 3.0.x.  </p>
  
  <p>To make my problem clear, I've taken the example from here <a href="http://www.sencha.com/examples/" rel="nofollow noreferrer">GXT 3 demo</a>, 
  here's how it is supposed to look:<img src="https://i.stack.imgur.com/OoJ9E.png" alt="Border layout demo">
  but when the same exact code from the example is copied into my project, it looks like this:
  <img src="https://i.stack.imgur.com/TLcuE.png" alt="same thing copied to my project"></p>
  
  <p>The layout seems to be broken. It renders the same in Chrome 22.0.x and Firefox 16.0.1.
  I use GWT 2.4 and GXT 3.0.1.
  My html page contains    </p>
  
  <pre><code>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"&gt;
  </code></pre>
  
  <p>and     <code>&lt;link rel="stylesheet" type="text/css" href="modeluname/reset.css" /&gt;</code></p>
