Title: Update the email validation regex. Do not update the email2 additional-methods regex.

I updated the email validation regex to combine the regex from djano and the original regex into something more robust. I did **not** update the email2 additional-methods.js regex nor the corresponding unit tests. References: https://github.com/jzaefferer/jquery-validation/issues/739
