Estimated JPG quality in browser

[PP0815]

I know that the Infobox contains the estimated JPG quality info but I think it would be great to have this info in the browser view via another column (in browsers details view).
Because (I guess) this will result in more processing time when a folder with many images is opened it would also be nice to have a checkbox in the preference (analyze estimated JPG quality for all images in folder: yes/no).
