Read item eq slots from the cache template

isTwoHanded, validForSlot, getSwingAnimation and the mob equipment set
read getItemEqSlotsOr/And, which drop the exporter's NONE. Offline parity
(p15c.py, 7586 rows): 0 differences once NONE is ignored.

Value changes:
- validForSlot: items whose only slot is NONE no longer pass for slot NONE.
- getSwingAnimation: the 7 slotless weapons (Rock 19297, Arrow 25650,
  siege ammo 29000/29010/29020/29030/29350) return the default 75 instead
  of indexing their empty left-hand anim list.
- MobBase equipment sets skip slotless items instead of keying them under
  NONE. No EQUIP booty entry references one (the 104 sets that do are ITEM
  booty sets).
