count true items (by Silver)
============================

The problem with count_items() is that it only counts the number of different
items you have. So if you have 1 pear and 1 banana it will correctly say you
have 2 items, but if you have 1 pear and 10 bananas its still says you have
2 (when it should be 11 items).

This function fixes this problem:

int count_total_items(player *p)
{
  item *i;
  struct s_item *s;
  int count = 0;

  if (!p->saved->item_top)
    return 0;

  for (i = p->saved->item_top; i; i = i->next)
  {
    s = find_item(0, i->id);
    if (!s)
      delete_entry_item(p->saved, i);
    else
      count += i->number;
  }

  return count;
}

an example of use of this could be:

  TELLPLAYER(p, "%s is carrying %d items\n", p2->name, count_total_items(p2));
