Invalid character in SMTP headers

[ghost]

This line of code
https://github.com/NatLibFi/Skosmos/blob/master/controller/WebController.php#L366
$headers = "MIME-Version: 1.0″ . '\r\n";
introduces an invalid quote that can cause SMTP servers to crash, as explained here :

It should be :
$headers = "MIME-Version: 1.0" . "\r\n";

Thanks, good catch! Looking at git history, this bug has been in Skosmos since the project transitioned from SVN in 2014, so it's pretty ancient.
