Feature: Generate RSS Feed from S3 Bucket Contents

[flamingquaks]

To expand the capabilities of the Data Feeds within the app, it would be nice to have a way to create a bucket, with bucket notifications that generate RSS Feed entries. When the RSS feed URL is hit, it should produce an RSS feed of the contents added to the bucket. This can then be consumed as a standard data feed in the application and then added to one or more newsletters.
