Use more fine grained access control

Browse source 
Make it possible to add more permissions to an object than just visible
or not. Pass these permissions to the client. This way we can make a
difference between being able to see and read, modify or query an
object. More permissions can be added later when needed. Because the
permissions is set on the resource by the access control module, the
implementations can check if the right permission is set before doing
anything.
