Add a persistent tag to entities spawned by the mob spawner.

Add a persistent tag to entities spawned by the mob spawner. This is the same sort of thing that Pneumaticcraft does and permits custom things to be done to entities spawned by the spawner via KubeJS, for example.

This is what Pneumaticcraft does, it's essentially the same thing. There doesn't seem to be a standardised (generic) way of indicating this, so this seems to do as good as anything else - though you might have a better idea for this.

Thanks for considering this.
