Humble Bundle notifier

[fisher60]

Summary

It would be nice to have a humble bundle notifier feature. We could allow users to subscribe to humble bundle alerts or just designate a channel to publish alerts in.

There is a public API available here

Example request:

POST https://isthereanydeal.com/bundles/api/list/
{"_id":1,"offset":0,"sort":null,"filter":{"bundleLive":true,"bundlePage":[1,37,9]},"options":[]}

As part of this feature, we should also review their ToS and ensure we are complying.
