title: What happened to ng-title directive in Angular 2?
body: <p>I had this code in Angular 1:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;div ng-title="item.favourite ? 'Remove' : 'Add'"&gt;
    &lt;i class="someClass"&gt; &lt;/i&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Angular 2 doesn't have a <code>[ngTitle]</code> and I didn't find anything related in the docs.</p>
  
  <p>Should I use <code>title="{{item.favourite ? 'Remove' : 'Add'}}"</code> or is there an "Angular 2 way"?</p>
