Change storage from {c1,c2,c3...} to {cat1: {c1,c2,c3}, cat2: ...}

DOM:
  Fix error in removing removed children

Store:
  AsyncResourceLoaderQueue - Made generic method for loading cached resources
  Model:
    async categories.load(id) - load category data with subitems
    async cards.load(category, id) - load full card data

    cards.load and new cards populate the same store. Useful for cache. Marked full data as `detailed`

Views:
  Product card display:
    InfoCard.jsx — display Item and back\next logics
    ProductCard.jsx — fill markup with data
    InfoPage.jsx — logics of loading data
