Show group ingredients visually in craft guide
Where a recipe specifies an ingredient by group, show a typical group item pictorially, with a label flag to indicate that it's a group rather than the single item. This is the inverse of the previous arrangement, which identified the group by label and dipicted groupiness pictorially. The new arrangement is easier to interpret, and if the labels are ignored it actually shows a correct input to the crafting grid.
