Added three utilities for admins & developers

- There is a new option in the player panel labeled "Send back to
   Lobby", which will send a given player back to the lobby.
 - The player panel also has a shortcut to the "Spawn Character" verb.
 - Finally, there's a new config option that disables the warning
   message about multikeying if two mobs with the same CID are found;
   this option should NOT be enabled if multikeying is prohibited by the
   server rules. It is simply a developer tool, as multikeying is
   sometimes necessary to test new features that require two clients
   interacting.
