Change vfs.php to allow a SSL only FTP Server

[DocSnyd3r]

Fixed my problem by replacing ftp_connect with ftp_ssl_connect in vfs.php. This also works if ssl is not enabled or required!
Now the choose dir function works again and users have to login via ssl and don't spam their ftp passwords everywhere. Added this info to the ticket where ftp server on non standard port is the issue.
