Hey, in this small patch I added some useful commands

• gms (Player)
  • Change a players gamemode to survival
• gma (Player)
  • Change a players gamemode to adventure
• gmc (Player)
  • Change a players gamemode to creative
• gmsp (Player
  • Change a players gamemode to spectator
• cleargrounditems
  • Clears all items on the ground
• clearmobs (EntityType)
  • Clears a specific type of entites

You are also now able to write %world% in a message, where player names (e.g. "playerRankNames") are used. %world% will be replaced with the world name of the player. It's now defaults in the chat formatter
