Nutrition and Ingredients Ratings

Better grocery store coverage. Products with plain names (like "Heirloom Rice Bowl") now score correctly on grocery sites such as Whole Foods, Wegmans, and ShopRite: being on a grocery store now counts as food context, and the food detector learned many more everyday foods (rice, pasta, soups, meats, produce, condiments). Non-food items grocers sell, like candles and paper goods, are no longer given nutrition scores. Fixes Whole Foods product pages not showing a score.
