title: jQuery Validation email rule
body: <p>With this simple email rule: </p>
  
  <pre><code>$("#loginCliente").validate({
      rules: {
          loginNomEmail: { required: true, email: true },
      }
  });
  </code></pre>
  
  <p>In this input field, if we enter "test@" we got the validate error. But if we enter "test@teste" the plugin show that is an valid email.</p>
