!weapons is no longer displayed in chat

It is annoying to have the whole chat spammed with !weapons all the time.
So I made a little plugin which replaces the "!weapons" command with the "/weapons" command so that is no longer visible in the chat.
I know that it could be helpful for new players to see !weapons all the time in the chat, but I don't mind.
You can still tell them "type !weapons in the chat"
