DynDNS does not update on settings change
services_dyndns_edit.php tries to delete /conf/dyndns_wanhe-netHOSTNAME.cache
Filename is actually dyndns_wanhe-net'HOSTNAME'.cache
Use correct filename.
Also, I would like to add a feature to separate the "Save" and "Save & Force Reload" into two separate options.
Patches for both issues coming soon.
