GoDaddy Updates

- Support for domains longer than 3 segments (ex. 1.www.mydomain.com).
- No need for GODADDY_BASE.  Domain will be automatically determined from full RR name.
- Update to delete challenge records.

-Using GoDaddy DNS for LetsEncrypt domain validation.
-
-Quick guide to setting up getssl for domain validation of
-GoDaddy DNS domains.
-
-There are two prerequisites to using getssl with GoDaddy DNS:
-
-1) Obtain an API access key from developer.godaddy.com
-   At first sign-up, you will be required to take a "test" key.
-   This is NOT what you need.  Accept it, then get a "Production"
-   key.  At this writing, there is no charge - but you must have
-   a GoDaddy customer account.
-
-   You must get the API key for the account which owns the domain
-   that you want to get certificates for.  If the domains that you
-   manage are owned by more than one account, get a key for each.
-
-   The access key consists of a "Key" and a "Secret".  You need
-   both.
-
-2) Obtain JSON.sh - https://github.com/dominictarr/JSON.sh
-
-With those in hand, the installation procedure is:
-
-1) Put JSON.sh in the getssl DNS scripts directory 
-   Default: /usr/share/getssl/dns_scripts
-
-2) Open your config file (the global file in ~/.getssl/getssl.cfg
-   or the per-account file in ~/.getssl/example.net/getssl.cfg
-
-3) Set the following options:
-   VALIDATE_VIA_DNS="true"
-   DNS_ADD_COMMAND="/usr/share/getssl/dns_scripts/dns_add_godaddy"
-   DNS_DEL_COMMAND="/usr/share/getssl/dns_scripts/dns_del_godaddy"
-   # The API key for your account/this domain
-   export GODADDY_KEY="..." GODADDY_SECRET="..."
-   # The base domain name(s) in which the challege records are stored
-   # E.g. if www.example.net is in the example.net zone:
-   export GODADDY_BASE="example.com example.net"
-
- 4) Set any other options that you wish (per the standard
-   directions.)  Use the test CA to make sure that
-   everything is setup correctly.
-
-That's it.  getssl example.net will now validate with DNS.
-
-To trace record additions and removals, run getssl as
-GODADDY_TRACE=Y getssl example.net
-
-There are additional options, which are documented in the
-*godaddy" files and dns_godaddy -h.
