title: override jquery validate plugin email address validation
body: <p>I find that jQuery validation plugin regex to be insufficient for my requirement. It accepts any email address xxx@hotmail.x as a valid email address whereas I want to be able to supply this regex /^([a-zA-Z0-9_.-+])+\@(([a-zA-Z0-9-])+.)+([a-zA-Z0-9]{2,4})+$/ so that it would validate complete .com part of the address. I'm more concerned about being able to supply my own regex than getting a fool proof regex(as there is no fool proof regex for email validation)</p>
  
  <p>Just FYI: I'm also doing server side validation but at this point I'm not worried about which email address regex is right.</p>
  
  <p>Is there a way to do that within the "rules" section of jQuery validate plugin?</p>
  
  <p>This is my rules section right now:</p>
  
  <pre><code>rules: {
                          email: {
                              required:  {
                                      depends:function(){
                                          $(this).val($.trim($(this).val()));
                                          return true;
                                      }   
                                  },
                              email: true
                          },
  </code></pre>
