Cake is food

create implication cake_on_head -> cake

not only is cake food, but cake is also cake

cake_hat also exists with another hundred posts. It says it's for hats that look like cakes, but there's a lot of real cakes too. Should probably be renamed to cake-shaped_hat or something.

rename cake_hat -> cake-shaped_hat

Will need some significant cleanup if we want to keep it separate.
