Title: Added ability to change the Kick Message displayed to players when the

Added ability to change the Kick Message displayed to players when the server is shutdown and expanded the /stop command to support this
feature.

Also added a temp shutdown kick message which sets the shutdown kick
message for that session, this is mainly used for the /stop
[kick-message] command.

When the server shuts down the temporary kick message will be shown if
it has been set, otherwise the one set in Bukkit.yml will be shown.
