RunTimeGraphEditor Does not set object as dirty when it's fields are changed.

[OdinKong]

Loving the add-on so far, but I was using it with scriptable objects recently and I realized it doesn't save any of the fields I'm changing when I save the project close and reopen the fields for the run time graph are all reset. This can be worked around by changing another standard field on the same scriptable object like a float and then saving and then changing it back. This causes the object to be set to dirty meaning unity's save project function will pick it up. Anyway I'm looking into adding set dirty to the editor script myself but I figured I should mention this.

Thanks again for making this it's super useful and cool!
