* Add support for notifying with Slack messages. When creating notifications, this allows you to pass in `attachments` with the `data`. It's an array of attachments as defined in https://api.slack.com/docs/message-attachments When passing in attachments, message is still required, but it's okay to be a blank string. * Split over multiple lines * Make sure attachments gets assigned, even if there isn't attachment data
