Fix incorrect Content-Type MIME headers of e-mail messages

Fix-mime-charset automatically detects character sets of email message and modifies the Content-Type header appropriately. It can be used as mail filter in mailing lists where users often set the charset of their messages incorrectly. It processes messages fast and accurately, ignoring attachments, and correctly interprets transfer-encodings. None but the Content-Type header is changed.
