Added flags for each ingredient group for the supplies state. On the main screen show the state of the supplies if the product stage is not yet packaged. Calculate the state of the supplies for fermentables, hops, yeasts and miscs. In the grids don't show the inventory values after they are used and reduced. On the fermentables tab show the weight of the grains to mash.
