title: jquery validation remote rule not firing
body: <p>i'm using jquery validation on my Registration form and have just added in a remote rule on the email field.  Everything except the remote rule/msg is working.  There's no call to check_email.php at all.  I've confirmed that I'm pointing to the correct .js file (not the .min.js).</p>
  
  <p>Here's a snippet.  Let me know if you want the whole validate function.  I'm using the submitHandler and it's working correctly, even preventing duplicate emails from being inserted, but I obviously want remote to function properly and don't know why it's not being called.</p>
  
  <pre><code>   $("#frmRegisterWebuser").validate({
    rules:{
           reg_email:{
                      required: true,
                      email: true,
               remote: {
                   url: 'check_email',
                   type: 'POST',
                   data: {'email': $('#reg_email').val()}
               }
              },
           username: {
                     required: true,
                     minlength: 3
                     },
  </code></pre>
  
  <p>Thanks!</p>
