missing label for form in services_dyndns_edit
services_dyndns_edit "Verify SSL peer" checkbox
doesn't show its corresponding form label. It is set to "null".
(So when the chexbox is displayed it may appear to be in the
"Verbose logging" section.)
I suggest it be set to "HTTP API options".
By the way, maybe curl_ipresolve_v4 form should be also
called "HTTP API options" as pfsense users shouldn't have to
know what "CURL" is.
