+//changes:
+//1-make the InstanceState a reference inside the resource that can be shared
+//2-make the instance "editable" with a flag, save here and load here, no need for property
+//3-properly save modifications in sub-scene
+//4-add scene inheritance
+//5-chain of instance states in editor? (to check what was modified)
+//6-saving will be hell
