artifact name formatting

Many (most?) non-weapon artifacts show up in inventory and messages
as "the <foo> of <bar>" even when their underlying object type hasn't been
discovered yet.  For types which don't use the `known' bit, obj->known is
forced to 1; obj_is_pname() checked that but not the oc_name_known flag
for the type.  So you'd see things like "the Heart of Ahriman" instead of
"a luckstone named <the H of A>" or "a gray stone named <the H of A>" even
though it hadn't been identified yet, unintentionally hiding the artifact's
object type from the player.
