Subject: Made Xom be smarter about being amused at losing/missing runes, and
 made Xom also be amused at runes being destroyed.  Related changes:

* Keep track of which items have ever been held by the player with
  ISFLAG_BEEN_IN_INV.

* item_was_destroyed() is called when an item is destroyed (as in
  dropped in lava, not destroy_item() being called), and item_was_lost()
  is called if the item was lost (i.e., being left behind in the Abyss).

* Keeps track of the number of runes that the character has collected,
  and how many have been left in the Halls of Zot.
