Mail::AddressListsParser can not parse

[ckarbass]

Looks like the parser isn't handling ñ or non english characters on Ruby 2.0.0 Rails 4

Also appears not to be able to parse Japanese characters.

I believe this is expected behavior -- the parser expects all headers to only contain ASCII characters. It assumes non-ascii characters will be encoded as specified in rfc2047. For example: https://github.com/mikel/mail/blob/master/spec/mail/encodings_spec.rb#L93

However, it looks like there are now some RFCs around the use of non-ascii characters in email headers that are finding being adopted: http://en.wikipedia.org/wiki/International_email#Overview_and_Framework_for_Internationalized_Email

I can take a look at what changes would need to be made to the parser to support 'international emails'.

@ckarbass @bonsaiben Could you provide examples of failing emails and the version of the mail gem you are using? Thanks!
