[Bug 15489] IDN email addresses should be converted to Punycode before validating them

As far as I can tell, many (most?) mail clients don't recognize IDN email
addresses and don't let you enter them into their UIs (e.g, into a To field) --
in particular, Web-based mail clients (Gmail for one).

Given that, it would maybe not be helpful to enable users to enter IDN email
addresses into validated form fields in Web apps until we are at the point
where more existing mail clients that are in common use actually also enable
that.

Ignore my previous comment. Ms2ger pointed out to me on IRC that the spec
actually says, "User agents may transform the values for display and editing;
in particular, user agents should convert punycode in the value to IDN in the
display and vice versa."

So the spec is already stating what you want, right? That is, that IDN email
addresses should be converted to Punycode before validating them.
