Improved product synchronization

Previously all products were fully retrieved once every night. For webshops with many products this could make the synchronization take a long time.

That is why we improved product synchronization considerably. ShopLinkr now synchronizes products incrementally. That means it only looks at what changed since the previous synchronization, instead of retrieving all products again.

The synchronization runs automatically every hour, but can also be started manually. In both cases ShopLinkr only updates the products that changed compared to the previous synchronization.

This makes product synchronization faster, lighter and much more efficient for webshops with large product catalogues.
