// @description  make ebay keinanzeigen usable. attempts to fade duplicates and items you have already seen once. has a high false possitive rate with current configuration where an item is keyed by only zipcode and price. I'd rather have higher false-positives and have adverts I miss then see an advert reposted with just a different title. This can bechanged though, see code below to change 'TAG'

// - removes all "pro" adverts
// - attempts to deduplicate 
// this last attempts to avoid the issue of ebay-kleinanzeigen sellers 
// always reposting same adds, making it impossible to monitor for new finds
