* New server event hook
onServerRename in the server config.ini set this to the bash script to call when the server is renamed. The string
$NEW_NAME$ will be substituted with the new name of the server. For example
onServerRename=echo 'New name is $NEW_NAME$' > /tmp/newname.txt
The above script script will write "New name is Server 1" to the file /tmp/newname.txt if the user renames the server to "Server 1"
