sitting_on_box implication

BUR #24686 has been approved by @nonamethanks.

create implication sitting_on_box -> on_box
remove implication sitting_on_box -> box

Someone sitting on a box implies someone is on a box. For things and people inside boxes, we have in box. Unimply box since it becomes redundant (on_box will imply it).
