Use Linode's DNS Manager API for one-line dynamic DNS

This can be useful for cron, for instance.

Prereqs

• You are using Linode's DNS Manager to manage a zone for your domain
• You have already created an A record for the name you want to make dynamic
• You have an API key for Linode's API
• curl and jsonpp (jsonpp is not necessary but makes the manual steps easier)
