RSS Connector needs setting to prevent same message being included repeatedly
It seems that for some RSS feeds the same message gets added to the Channel every x hours (depending on polling frequency).
Can confirm this problem, I have one feed that for each new item adds it to the channel 1-4 times. Same headline, same publishing time but small changes in text like spelling corrections.
In most cases headline and date might be enough to compare while ignore text content. Maybe there could be an option under configure to only compare headline/publish date when determining if the item has already been received.
