Google tasks rollover

Run this script to roll over all overdue Google tasks to the current day. Annoyingly, will open a browser tab each time it runs (see https://www.npmjs.com/package/google-oauth2 for reasons).

In config.json, provide

{
    "client_id": <your Google client ID>,
    "client_secret": <your Google client secret>,
    "task_list": <the ID of your task list>
}

And then,

npm start
