title: Validation plugin - Auto validate multiple forms on a page
body: <p>Currently I need to validate every form like this:</p>
  
  <pre><code>    $(document).ready(function () {
          $('#admin_settings_general').validate({
              rules: {
                  admin_settings_application_title: {
                      required: true
                  }
              },
              highlight: function (element) {
                  $(element).closest('.form-group').addClass('has-error');
              },
              unhighlight: function (element) {
                  $(element).closest('.form-group').removeClass('has-error');
              }
          });
      });
  </code></pre>
  
  <p>I want that it automaticly validate the forms for every element with the <code>required</code>  tag.</p>
  
  <p>How can I do that?</p>
