RuntimeDialogueGraph doesnt save actor data

[123tris]

Any changes made in RuntimeDialogueGraph.PersistentData.ActorData is not saved, making it impossible to utilize custom actor data.

I've solved this in my fork for development since I wanted to redo the inspector editor anyways. But I think in general having this data attached to the monobehaviour is a bit problematic. I think ideally all this data should be part of the actual graph object instead. If universal checknames/triggers/actor names are desired then separating that makes sense but will need some unified way of accessing that. (could be another separate scriptable object, could be a editorwindow/setting thing. etc.)
