  ItemColor, ItemClassicCollar, ItemShockCollar, ItemShockCollarAuto,
  ItemGpsCollar, ItemChokeCollar, ItemHood, ItemMedicalGag,
  IBondageItem, IHasGaggingEffect, IHasBlindingEffect, IAdjustable

D5: Deleted 11 variant enums + Generic* factories + ItemBallGag3D:
  BindVariant, GagVariant, BlindfoldVariant, EarplugsVariant, MittensVariant,
  GenericBind, GenericGag, GenericBlindfold, GenericEarplugs, GenericMittens
