Use product controller for products

[knitzie]

We don't use the product object and controller for simplicity. That's why we have to edit the file <projectPath>\custom-sofa\bower_components\sofa-basket-service\dist\sofa.BasketService.js
Remove lines 100 till 102 (comment them out)

if (product.isOutOfStock()) {
    throw new Error('product out of stock');
}

Else you get this error:

TypeError: undefined is not a function
    at Object.self.addItem (http://localhost:9000/bower_components/sofa-basket-service/dist/sofa.basketService.js:100:21)
