media uploader image order backwards

The media uploader has always taken a list of files, say 101 to 150, and displayed them with 101 on the bottom, and 150 on top in the media list (last uploaded first). It’s backwards from the way the files will be used, but hasn’t mattered much, as the gallery shortcode allowed orderby name. Now with the new gallery manager to re-order images they are all displayed in that order, with the last file uploaded coming first.
