{Feature} Make Hotspot Objects a property of the Material

[Sayayaya]

I think it would be cool if the hotspot object was directly tied to the material some how. This way we wouldn't need to constantly pick the object all the time.

Maybe in such a way that such a material was portable between .blend projects? ie appending the data would bring the hotspot object along for the ride.

This is something I have long planned and hope to get around to some day
