Title: Updated email regex to support 11 character TLDs

New TLDs are coming end of January that increase the maximum length of existing TLDs to 11 characters. (.PHOTOGRAPHY). As such the regex for validating email addresses should change, I don't know when to submit this pull request (how close to the open registration date), but I've had to make this change internally to preempt general availability.
