World's Coliding

**__Version 1.1.4 :__**
> 
> - Removed When dungeons arise & Seven Seas (felt too op and redundant)
> 
> - Added  a new structure progression system, now main structurs are in a list, accesible with /list_structure, it shows which structues are unlocked. Trying to access to an unavaible one will lead to an in game warning before death. Structures arre unlocked via the quest book, depending of the story progression, making it impossible to skip or cheat throught the story.
> => When in an non unlocked structure, get blindness and darkness before taking lethal damages. When in an unlocked structure, you cannnot break nor place blocks, except tnt which can be placed and used to destory blocks. Futhermore, in the listed structures, mobs will have poportional health as to the chapter you are supposed to explore them, so you don't just one tap everything and have some challenge. 
> => If you notice any structure which isn't listed when it hshould, or if you find mobds in one who dont have the right health, please tag me.
>
