ListDuplicatedFilesPage::getQueryInfo ( )

Get all the duplicates by grouping on sha1s.

A cheaper (but less useful) version of this query would be to not care how many duplicates a particular file has, and do a self-join on image table. However this version should be no more expensive then Special:MostLinked, which seems to get handled fine with however we are doing cached special pages.
