2014511937 - Improved the functionality of the ERC provider import action

In the action “Import data from an ERC provider” there is a field for selecting provider categories. Previously it worked like this: in the field, select the categories of OneBox products and if their name matches the name of the supplier's category, the products are added; now: also select the categories of OneBox products, then the products of the selected categories are checked by article, if the supplier has a product with this article, the information from the supplier will be updated in the box.
