country: two-way binding

[Zaitsev]

First commit will update country in controller with intlTelInput current country iso-2 code (on flag select or when user type number) Second commit is to update intlTelInput to latest 6.4.3(it uses cookies to reduce api-calls to geoIP DB)

when ipnConfig.defaultCountry = 'auto'; I have to add

         ipnConfig.geoIpLookup= function (callback) {
                $.get('http://ipinfo.io', function () {
                }, "jsonp").always(function (resp) {
                    var countryCode = (resp && resp.country) ? resp.country : "";
                    callback(countryCode);
                });
            };

may be we can add this as default and with angular $http ?
