The DynDNS wildcard option doesn't work for provider Loopia.

It seems that this line never results in $this->_dnsWildcard being set to "ON":

if (isset($this->_dnsWildcard) && $this->_dnsWildcard != "OFF") $this->_dnsWildcard = "ON";

The same check is done for many providers, so maybe this problem doesn't only affect Loopia.

Here's a fix for Loopia, that works for me at least:

case 'loopia':
    $needsIP = TRUE;
    if(isset($this->_dnsWildcard) && $this->_dnsWildcard == TRUE) {
        $this->_dnsWildcard = "ON";
    }
    else {
        $this->_dnsWildcard = "OFF";
    }
    curl_setopt($ch, CURLOPT_USERPWD, $this->_dnsUser.':'.$this->_dnsPass);
    curl_setopt($ch, CURLOPT_URL, 'https://dyndns.loopia.se/?system=custom&hostname=' . $this->_dnsHost . '&myip=' . $this->_dnsIP . '&wildcard=' . $this->_dnsWildcard . '&mx=' . $this->_dnsMX . '&backmx=NO');
    break;

Please note that the host(CURLOPT_URL) is changed to https://dyndns.loopia.se, as stated on Loopia's support page:
