Feature request: run Symbol Organizer automatically on specific events
[Artboard manager](https://github.com/bomberstudios/artboard-manager) has this feature where it just reorders the artboards when you drag and drop them. 

It would be great if Symbol Organizer would do so we don't need to press the shortcut :).

The plugins' manifest has the following events registered, together with their handlers:
```
"handlers": {
        "actions": {
          "ArtboardChanged.finish": "ArtboardChanged",
          "LayersMoved.finish": "LayersMoved",
          "Duplicate.finish": "Duplicate",
          "HandlerLostFocus": "Resize",
          "ResizeArtboardToFit": "ResizeArtboardToFit",
          "InsertArtboard.finish": "InsertArtboard"
        }
      }
```
