Update 15 - World Map (YEAH!)

Added a world map that connects the levels. I needed to refactor most of the level data structures as I needed to get level information without the need of loading the whole map. 

During that process the idea grew to let the characters travel the world while unlocking new levels. 

The Path2D in Godot is a lot fun and it was easy to do a path we can edit with ease and move the characters along it. There is great potential for some funny things. 

Next I will work on the map unlock progress and properly implement a 3 star reward system and amount of stars you need to unlock certain maps. It is also time to look more into animation and fresh maps.
