Add Tag, SpecialCake, Cake.Tags, Order.SpecialCakes types. Add migrations for tag, cake_tag, special_cake, special_cake_tag tables. Add store methods: GetTags, GetCakeTags, SaveCakeTags, CreateTag, GetSpecialCakes, GetSpecialCakeTags, SaveSpecialCakes, saveSpecialCakeTags. Load tags in GetCake/GetCakes, cascade tag saves in SaveCake. Remove debug log calls from ParsePrice.
