David Négrier 0e68490e75 Refactoring with a MapStore
A great deal of the complexity of the current code is that we must chain
2 reactive values (one in the map "GameScene.MapPlayersByKey" and one in
the snapshot store).

The new generic MapStore class can be used to listen to stores inside a map.
When the store inside the map, or the map itself is modified, the
resulting store is updated.
