V2 Flickr interestingness and groups

Displays the groups containing the 500 interesting Flickr photos for any given day based on user input. List view sorts in descending order the Groups w/ the number of Explore photos the group has that day; also shows the ranked Explore photos. I still need to map the photos to the groups and display them, but this is a start. This pipe is based on Alto Maltes' 'Flickr – In which groups’ pools are my photos?' pipe.
