Filtering duplicate feed update news based on url

[bw4518]

In case I haven't overlooked this, I'd welcome an option to not add the news again, if only the title/description/etc changes, but the url is the same.

Yeah I would like this as a new feature! Time consuming going through two or three copies of the same feed article!

I too find this feature very useful. Thanks for any suggestion how to address it!
