 * - Blank maps.  We create one per level of the main dungeon.  With
 *  the maps created in the player's inventory, this is enough to map
 *  the whole dungeon.
 *
 * - The Crown of Yendor.
 *
 * - Rings of flying, water breathing, fire resistance, and phasing on
 *  the bottom four levels of the dungeon.
