The generator stored wiki unknowns as real values and dropped several fields tool builders need. Loot min and max, -- costs and is_boss are unchanged, and servers from 0.2.0 to 0.17.5 read the new index without errors.

changes:

• read paraimmune the right way round and stored ? stats, flags, costs and modifiers as NULL instead of 0 or false
• added item slot and is_usable, spell spell_id, creature attack_type and uses_spells
• kept every item client id in item_client_id
• kept loot rarity through the Loot Statistics task and the kills it used
• kept Haste, Debuff and Outfit abilities and ability conditions
• moved Mapper Coords out of locations into coordinate tables, and added item location and trade_value_note
• made untrusted location and note text unable to crash or stall a run
