title: jquery Validate errorPlacement insert element + br + error
body: <p>I'm trying to use 'errorPlacement' from jQuery Validation DOCS, like that:</p>
  
  <pre><code>$("#myform").validate({
      errorPlacement: function(error, element) {
          error.insertAfter(element);
      }
  });
  </code></pre>
  
  <p>So far so good, but what I really want is to insert a <strong>&lt;br /&gt;</strong> tag between the input and the error label in each case:</p>
  
  <pre><code>&lt;input&gt;
  **&lt;br /&gt;**
  &lt;label class="error"&gt;
  </code></pre>
  
  <p>I have tried with:</p>
  
  <pre><code>error.insertAfter(element.append($('&lt;br /&gt;'));
  </code></pre>
  
  <p>...but no luck. Is there a simple way of doing it? 
  Any help is much appreciated.</p>
