Re-enable Salvagers on Classic

[Kotlol]

We could try it I guess, salvagers have got a lot stronger/faster since release but my memory of salvagers on classic was basically nothing happening for 40 minutes while they scrapped every inch of the debris field and then came on station to rampage at the end.

Just make it so they can't do that in the debris field.
We blocked vampires and changelings getting points from the Diner.
