feat(inventory): equip and unequip like live

Live, on every equip and unequip (captures: 22,422 ChangeObjectWorldState,
4,269 equip effects, 245 UncastSkill):

- ChangeObjectWorldState on the item to everyone: ATTACHED when equipped,
  INVENTORY when unequipped, proxies (sub-items) included.
- The equip-<slot> / unequip-<slot> effect on the wearer to everyone
  (effect -1, priority 1.07), the slot picked from the item's equip location
  as the client's ItemComponent does (0x00cdafb0): special_l left,
  special_r right, hair head, clavicle, chest, legs; none for others (e.g. a
  rocket's Extra_1); the item's equipEffects with "equip"/"unequip" when it
  has one; no equip effect for noEquipAnimation items, no unequip effect for
  proxies.
- Order when an item replaces another: the new item's state and effect,
  then the old item's, then the old item's proxies taken away
  (RemoveItemFromInventory, UnEquipInventory with ignoreCooldown,
  ChangeObjectWorldState INVENTORY, to the player), then UncastSkill for
  the old item's equip skills (castOnType 1, not its proxies'), then its
  skill removed and the new one added, then the new item's proxies.
- An equipped item taken out of the inventory is followed by
  UnEquipInventory (ignoreCooldown) to the player.

DLU sent none of these (only the rocket's ChangeObjectWorldState, which
now comes from equipping it, before RocketEquipped as live).

Check in game (with a second player watching): equip and unequip a hat, a
sword, a shield, a shirt, pants and a backpack; both players see the equip
animation/effect. Put a ninja hood on, then another hat over it: the hood's
back piece disappears and its passive effects end (no lingering aura or
stat). Launch a rocket: it is still shown during the launch.
