Showing vitamins either always as % or as both % and weight when the weight is defined in JSON

[Karol1223]

So currently if a comestible has vitamin defined by weight in the JSON, HHG shows it in weight units. Ingame it's shown in both weight and % alongside one another. It'd be handy if we could use HHG to see how the weight translates to % without opening the game (or... I mean, calculating it by hand. Yes, I am lazy)
