Hello there,

again I fixed couple of bugs:
- Bug of getting teleported underground when trying to teleporting to own world and is still creating
- There was a new message for this added: In the configs it is world.still_creating
- I added a message when a player tried to open the player gui and no one was added, path: member.no_one_added
- And the "Your world is now ready.." message gets first then send if the world is really ready and a message that the world is setting up is sended before
- Fixed with a full recode some bugs at the CommadListener
