Incorrect decode UTF-8 encoded mail address

[cshrper]

bug occurs when I load Message from ".eml" file, that has been created some other program,
and it has the MailAddress encoded in UTF-8,
for example:
I got decoded value "Лучшему кл��енту jane@contoso.com"
instead of "Лучшему клиенту jane@contoso.com"

you can test old version with headers:
X-Sender: =?utf-8?Q?=D0=A3=D0=B2=D0=B0=D0=B6=D0=B0=D0=B5=D0=BC=D1=8B=D0?=

Hello and thank you for your pull request. Is it possible that you could change the indentation to tabs and add a test case such that that this bug will not be reintroduced again? Then I would merge the pull request.

No, I do not change any thing. I just do so:
var to = new MailAddress("jane@contoso.com", "Лучшему клиенту");
var from = new MailAddress("ben@contoso.com", "Уважаемый поставщик");
var message = new MailMessage(from, to);
message.To.Add(new MailAddress("alex@contoso.com", "Лучшему другу лучшего клиента"));
message.Subject = "Используем новый SMTP клиент.";
message.SubjectEncoding = Encoding.UTF8;

message.Body = "Using this new feature, you can send an e-mail message from an application very easily.";
message.BodyEncoding = Encoding.UTF8;
var smtpClient = new System.Net.Mail.SmtpClient { DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory };
smtpClient.PickupDirectoryLocation = tempDir.DirectoryPath;
smtpClient.Send(message);

And then I try to load message:
var msg = OpenPop.Mime.Message.Load(new FileInfo(Path.Combine(path, "Test.eml")));

This patch is broken. The patch assumes that each encoded word token uses the exact same encoding and charset values, but neither are guaranteed to be the case.
