Vanilla Clans

Hello, this is the first version of my plugin. I hope you'll give me feedback so I can improve it! Usage: /clan create - command to create a clan. If you don't specify a color, it will be white by default. /clan info - displays information about the clan you're in. /clan delete - deletes a clan if you own it. /clan kick - kicks a player from a clan if you own it. /clan invite - invites someone to join a clan. /clan accept - accepts an invitation. /clan refuse - declines an invitation.
