ACLs for viewing and creating Resources

This commit allows any authenticated user to view and create any
Resources
Restrict access to Document and Binder with ACLs
Refactor derive content and resources code
Allow users to publish revisions of something from archive

The way to create a draft from something in archive is to POST to
/users/contents with the archive content id.  For now, if the username
of the logged in user and the submitter of the archive content match,
then a draft will be created, otherwise you get 403.  If the id is not
found in archive, you get 404.
