Gmail and Yahoo not receiving messages

[icefront]

I had to change the encodeUtf8() function to receive messages on Gmail and Yahoo:

public function encodeUtf8($value) {
	$value = trim($value);
	return mb_detect_encoding($value) === 'ASCII' ? $value : $this->encodeUtf8Word($value);
}

@eoghanobrien: Do you think this worth a pull request?

@icefront: Would you create an example to demonstrate the problem?

@k00ni Yes, a pull request that passes the tests and adds a test for this case would be accepted.
