core81: add changes to core81 updater.
ddns.cgi: Fix enable/disable handling of entries. When the "enabled" checkbox is checked a "on" will be returned, if the box is unchecked checkboxes will return nothing. As a result of this behaviour the ddns.conf contained entries which have been disabled in the WUI. We now check if the checkbox returns a "on", otherwise we will set the "enabled" value to "off" to prevent from this problem.
ddns.cgi: Fix token auth for provider regfish.com. In the past the regfish.com auth token was stored as username similar than freedns.afraid.com. We now expected the token key stored as password, to keep compatiblity with old installations I've added some compatible code to prevent users from various issues.
