Stacking vs Stack

BUR #15046 has been rejected.

remove implication human_tower -> stacking
create implication human_tower -> stack

Stacking should refer to the action of making a stack, while stack should be already made. Examples of proper stacking usage:

• post #5251180
• post #5928650
• post #5859291
• post #5349556
• post #5325597

However, there's a lot of overlap between stacking -stack and -stacking stack currently. I suggest making the distinction clearer. We can start by changing human tower to imply stack instead, since they rarely depict the action.

BUR #15047 has been rejected.

create implication pancake_stack -> stack
create implication plate_stack -> stack

And some additional clear implications.

I'm not sure what to do with human stacking though.
