Email fix for #3755

[ScopeyNZ]

In the end I did a bit of research and borrowed the email regex used in angular.js.

Seems that this regexp is more accurate: (I forgot the source though)

/^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i

If it works for angular it works for me

@kevinresol If you can qualify the differences in your regex I would consider.

@jlukic in the link I posted previously you can press "Build + Run" to try it.

You should be able to notice that k.@cc.com is considered as valid email address by angular's regex while it should not be. And my suggested regex correctly recognize that.
