Rejected access to jcr:content from the web ui for NOT_FOUND (status 404)

I think the major issue is that the FedoraNodes.java allows the access to any methods in the class with no path restriction. I've added functions to reject all access ended with jcr:content for status not found. Now we'll see the jersey 404 error message if a user try to access any resources with jcr:content.
