Notes

• [GitHub] Apparently it's now possible to define a single hook for all activities within an organization: https://developer.github.com/changes/2014-12-03-preview-the-new-organization-webhooks-api/ — that means we might be able to set that once per API/OAuth call and have a single catcher for all GitHub-related things (no more forgetting to configure channel notifications for new repos e.g.). Also, notifications for not just commits, but other activities as well.
