Allow players to list users by default

The rationale for not allowing players to list users in the cluster by
default was that this would be an information disclosure of banned users
in the cluster, but given that a player is a user that can connect to a
server, and anyone that can connect to a server get the full banlist
from the server during the connection phase this does not make much
sense.  Grant permission to list users by default for players.
