display affected groups on flag

affected groups are displayed after command " /drg flag region [flag-name] [variable]"
the return is typically
"[region-name] set [flag-name] to [variable]"

Would be better as
"[region-name] set [flag-name] to [variable]. ( affected groups )"
i.e. "spawn set hunger flag to deny (owner, member, nonmember)"
