Adding a notion of instances per mapAdding a notion of instances to room

The URL signature becomes:

https://workadventu.re/_/[instance]/[path_to_map.json]

This allows us to create many instances of the same map (and therefore to create several different worlds for different people)

An exit on a map can target another "instance" by passing the "exitInstance" property.

In order to place an on your scene that leads to another scene:
- You must create an specific layer. When a character reaches ANY tile of that layer, it will exit the scene.
- In layer properties, you must add "exitSceneUrl" property. It represents the map URL of the next scene. For example : `/<map folder>/<map>.json`. Be careful, if you want the next map to be correctly loaded, you must check that the map files are in folder `back/src/Assets/Maps/<your map folder>`. The files will be accessible by url `<HOST>/map/files/<your map folder>/...`.

The files will be accessible by url `<HOST>/map/files/<your map folder>/...`.
- In layer properties, you CAN add an "exitInstance" property. If set, you will join the map of the specified instance. Otherwise, you will stay on the same instance.
- If you want to have multiple exits, you can create many layers with name "exit". Each layer has a different key `exitSceneUrl` and have tiles that represent exits to another scene.
