This commit makes it possible for players to set an afk message to detail their reasoning for being away to other players. This can be especially useful for the /msg command; instead of replying the user is afk, it will specify why they are afk so the sender can act further on that information.
Two methods have been added to IUser: getAfkMessage() and setAFKMessage(String).
All locale files have two new messages: userAFKWithReason and userIsAwayWithReason. They all use the messages that do not have the suffix WithReason, i.e. userAFK and userIsAway. Furthermore, the userIsAwayWithReason will not utilise the second parameter, the reason, to prevent spam and unnecessary text in global chat. However, the second parameter ({1}) is available for use in userIsAwayWithReason. userAFKWithReason, which is sent to /msg senders, does use the {1} as it controllable spam by the command sender themselves.
/afk usage is now: /afk [player/message...]
Add translatable message recentlyForeverAlone.
Add behaviour that preserves reply-recipient only if they are reachable, and update reply-recipient if they are not reachable.
Fixes#248
This commit adds a new boolean-configurable feature called last-message-reply-recipient, defaults to true for new installs and false for old installs, which states whether to use the new messaging functionality or not.
This commit deprecates Console#getCommandSender(Server) and provides Console#getInstance()#getCommandSender() for future usability.
