What is the issue?: Calling the Spigot parameter help menu with java -jar spigot-jar --help or -? gives back an "outdated" list of all startup parameters. How to improve/fix?: Update this little help menu to include the -Dorg.spigotmc.netty.disabled=true parmenter and remove the -online-mode one since it doesn't exist anymore. Just a little cosmetic change but it would avoid confusion by users that actually use this parameter help menu.
