Subject: provide a DAV module which accesses the raw data storage for a
 channel. Together with an export data function in the API this allows a
 client process to create true backups of the cloud storage and importable
 cloud mirrors with all the metadata intact. The import function will need to
 be modified slightly to obtain the file contents from a plugin or API call;
 since it currently tries to fetch it from the source hub.
