Add DynDNS No-IP Free account support
The free No-IP account requires the IP address to be changed within every 30 days. If there is no change, the "last updated" date at No-IP does not get updated and the account lapses.
This change implements a double-update when the cache age reaches 25 days, or the user does "Save & Force Update" on the GUI. It updates the IP to a dummy address (192.168.1.1) and then 10 seconds later puts it back the way it was. After this process, the "last updated" date on the No-IP site updates.
To get this behavious, users have to select "No-IP (free)" as their DynDNS service type.
