Fork with TTL update and ipv4 or ipv6 passed as command line arguments

[jeromecc]

Just in case anyone is interested... https://github.com/jeromecc/Digital-Ocean-Dynamic-DNS-Updater/tree/ttl Thanks for the good job. I am using the modified version of your script inside my Ansible playbooks because current Ansible DO domain record modules cannot modify TTLs. Default TTL of 1800 seconds is far too high to test my developments quickly (they include frequent creation and destruction of droplets... time is money! ;-)
