Subject: A new REST resource that allows access to view and modify the actual
 contents of the file, which enables REST viewers to see the actual data which
 is useful when the files are privileged.  Currently it returns the contents
 of the file in JSON encoded form, which may not be the best.  Multipart/mime
 might be much better.

Fixes ticket #1224.
