A feature has been added for admins to set a specific join/quit message for players. A help command has been added to find out the available commands. A new permission 'customjoinandquit.admin' has been added.
Added the option to change the join/leave message for each player. All player join/leave messages are stored in the file 'player-custom-messages.yml' under the player's UUID. The UUID of each player can be found using '/cjqr info <nick>'.
