/nic/delete API url

The dyndns2 standard does not give a means to delete a DNS record (like A or AAAA), you can only update to a new address using /nic/update.

Thus, we created a /nic/delete URL that behaves just like the dyndns2 update api, but removes the A or AAAA record in DNS instead of updating it.

While the update API would actually use the given IP address to put it into an A or AAAA record, the delete API uses it only to determine the address type, whether it is IPv6 or v6 and then deletes the A or AAAA record.
