Fatal error: Class 'TYPO3\SwiftMailer\Message' not found

[KatharinaSt]

This line in the EmailFinisher class does not ensure that the required Swiftmailer class is actually available (and causes a fatal error if you don't have Swiftmailer installed):
$mail = new \TYPO3\SwiftMailer\Message();

I suggest to either include Swiftmailer as dependency in composer.json or to check for installed Swiftmailer and throw an informative exception instead.

Thanks, good point! I guess we should at least suggest the switftmailer package if we don't want to create a hard dependency.

Fixed with #23
