Title: Bug 2591 - Prepare projects to be fronted by the clouds

This patch prepares our S3 code to be put behind the CloudFront CDN service by:
* Providing cache-busting URLs to the share editor
* Passing cache-busting URLs through the embed shell to the embed
* Added configuration option to pass arbitrary headers to S3 when writing an object
* Documentation for the S3 changes
