title: jQuery Form Validation plugin with multiple rules
body: <p>I'm using the jQueryValidation plugin. <strong>Problem</strong>: I would like to use multiple pattern rules within for one input field. E.g.:</p>
  
  <pre><code>$("form").validate({
   rules: {
      "email": {
          required: true,
          email: true
      },
      "password": {
          required: true,
          pattern: /^[A-Za-z0-9\w]{4,20}/,
          pattern: /^[\d\w\xC4\xD6\xDC\xE4\xF6\xFC\xDF]*$/
      }
   }
  });
  </code></pre>
  
  <p><strong>What happens</strong>: the plugin tests only the second pattern rule. E.g. entering something like "tst" works (as this fulfils the seconds pattern) although it violates the first pattern rule.</p>
  
  <p>As far as I understand the logic of rules in this plugin, all rules have to return TRUE in order to validate a form.</p>
