/f banlist and /f invitelist - change these to show an actual list

This is a very small thing (low priority, bans feature is potentially useful but likely rarely used, invites may expire anyway but not sure) but an idea. These commands don't actually list the number of bans/invites, they simply list the NUMBER of bans/invites, which isn't very helpful (might be a bug, but not sure). I think it would be more useful if these commands listed banned/invited players, rather than simply giving you a number and no way to view the list.
