Feature Request: Toggle all the 1st Duplicates

[brock]

Have you ever thought about adding an option at the top of the results screen along the lines of "Mark each 1st photo as a duplicate". It seems like we'd have to collect all the photo id's and batch the request.

I'm about to head out, but a quick glance through the code looks like each duplicate "tag" is an html link that sends the tag instructions to Flickr individually, but if you'd be open to something like this I might fork and see if I can get this working.
