Wish: Better Replace dialog

Hello,


I wish we could have a better UX on the Replace dialog.

Suggestions to improve this significantly:


 1. Tell me how many images are conflicting. Is it just one or thousands?
 2. Let me opt to go through them one by one and decide what to do.
 3. Digikam is about handling *photos*. At least let me see the
    conflicting images side-by-side and choose what to do, what image to
    keep, rename, etc.
 4. Give me an option to see details about the conflicting image files.
    Things like filenames, file sizes, modification date, etc. are vital
    for the user to make a decision.


Please consider implementing these.


Thanks!
