Allow + and - in non-capturing domain group

[arxpoetica]

These characters are common to domain names.

Sorry this has been sitting for so long, i'm seeking new maintainers, let me know here if you're interested: #72

RMC952 States:

A "name" (Net, Host, Gateway, or Domain name) is a text string up
to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus
sign (-), and period (.).

I don't think a plus sign is valid in a domain. Can you find data that says otherwise? If not, can you drop the plus sign from the regex?

Thanks

Update the regex like so:

email: function (val) {
    var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
    return re.test(val);
}
