BUR #6811 has been approved by @evazion.
create implication book_hug -> object_hug
create implication doll_hug -> object_hug
create implication pillow_hug -> object_hug
They are all object hug, the only inconsistency I can see is that the hugged object can also be an animated object, especially dolls.
Should the wiki changed to say "animate and inanimate objects", or the current way is fine?
