enterRoutine needs to work with piles

[96LawDawg]

In a holder that has piles, an enterRoutine works for the first card. Cards after that enter the pile and not the holder. But just like we do with other pile areas, VTT should look past the pile and pretend it is not there. I think this could probably be game breaking, so maybe what we need to the file updater is not ridiculous is an ancestorEnterRoutine that works like _ancestor does for parent.
