Backward compatibility with older versions

Versions up to this commit did not use the variable $no_expire_token:

Line 77 in b3b8233

    
           list($extra_info, $hide_name, $expire, $referer, $email, $zombie) = explode(self::SEPARATOR_EXTRA, $extra);

Fix this line:

Line 506 in 9ccd381

    
           list($extra_info, $hide_name, $expire, $referer, $email, $zombie, $no_expire_token) = explode('#', $extra);

By:

list($extra_info, $hide_name, $expire, $referer, $email, $zombie, $no_expire_token) = array_pad(explode('#', $extra), 7, null);

hey?
