fix #H7865 - shop prices for container contents

Browse Source 
The recent attempt to have looking inside a container show shop
prices had multiple problems.  Worst one was showing shop prices as
if the hero would be buying for items already owned by the hero.
Item handling inside containers on shop floor was inconsistent:  if
shop was selling those items, they would include a price, but if not
selling--either already owned by hero or shopkeeper didn't care about
them--they were only marked "no charge" if hero owned the container.

This is definitely better but I won't be surprised if other obscure
issues crop up.  Gold inside containers on shop floor is always owned
by the shop (credit is issued if it was owned by the hero) but is not
described as such.
