Station authority level "L,S,S+R,L+S,L+S+R"

Station authority level "L,S,S+R,L+S,L+S+R" adds station control access together
with several different multilevel access scenarios. Control access can also be
simultaneously permitted from local, station or remote location. Simultaneous local,
station or remote control operation is not allowed as one client and location at time can
access controllable objects and they remain reserved until the previously started
control operation is first completed by the client.
