[Typo3] Proper e-mail encoding for extensions

[Jan Bednarik]

Hi,

> config.notification_email_charset = UTF-8
They use the htmlmail class, not the notification mail function. 
Therefore this doesn't work. Update your class.t3lib_htmlmail.php from 
here http://www.bednarik.org/uploads/media/typo3_3.8.0_changes.zip and 
your e-mails should use forceCharset value as encoding.
