title: Angular filter that generates html
body: <p>I have a small angular filter that insert an (bootstrap) icon in place of a true value.
  It works but the html is encoded:</p>
  
  <pre><code>  var conApp = angular.module('conApp', []);
    conApp.filter('trueIcon', function($filter){
      return function(booleanValue){
          return booleanValue ? '&lt;i class="icon-ok"&gt;&lt;/i&gt;' : '';
      }
    });
  </code></pre>
  
  <p>Do i have to implement another filter to decode the html ?
  Is there an "angular" way of doing this ?</p>
