Use 3D models instead of item icons when available for food placed on Cutting Board.

I have kinda decided against this idea, mostly due to how it would display short models against the full block ones. Sorry :(

Determining which items have a block to display isn't super easy; some of them would look wacky on the Cutting Board if I made them all display the block form (example: Wheat Seeds would look like the crop on age 0).

I might take a look later; maybe special-case it to pies and cakes, which are the main target here

Would a farmersdelight:show_block_form_on_board tag work here? You can never have too many customization tags :D
