Title: HTML5 compatible regex for emails

Now matches the HTML5 spec for input type="email":
http://www.whatwg.org/specs/web-apps/current-work/multipage/states-of-the-type-attribute.html#e-mail-state-%28type=email%29

Also note that this does not actually validate against all possible emails although it is a good approximation for the majority of users (see here for more: http://stackoverflow.com/questions/201323/how-to-use-a-regular-expression-to-validate-an-email-addresses).

An example of an email which will now validate (that is actually valid) but would not before:
hello@io

Note: This is for the english translation only.
