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.
