  Sleeping Bull Inn, Mad Mage Isle/Erstam, Furnace,
  Great Northern Forest, Monk Isle, Dream Realm/Gorlab Swamp,
  Gwani/Ice Areas, Shamino's Castle, Skullcrusher, Spinebreaker,

Rename 9 flags for accuracy (updated in both globals.uc and usecode.uc):
  FEBABIBLIO_SAVED -> FEDABIBLIO_SAVED (typo)
  ASK_ONLON_GWANI -> ASK_OLON_GWANI (typo)
  KNOWS_KRAYG_WALKS_ON_WOODS -> KNOWS_KRAYG_WALKS_IN_WOODS (grammar)
  GAVE_WOLF_TO_CELIA -> GAVE_WOLF_TO_CELLIA (NPC spelling)
  PLACED_SOUL_PRISM_MADNESS -> PLACED_SOUL_PRISM_INSANITY (correct Bane)
  ARENA_BATTLE_STARTED -> FURNACE_ARENA_BATTLE_STARTED (location prefix)
  AVATAR_IN_BEDROOM -> AVATAR_IN_SPINEBREAKER_BEDROOM (location prefix)
  MASTER_SWITCH_IS_ACTIVE -> SILVER_SEED_MASTER_SWITCH (location prefix)
  PRESSED_BOTH_SWITCHES -> FREEDOM_PRESSED_BOTH_SWITCHES (location prefix)
