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.
