- Integrate the patch from Matthias Fuchs from http://reviewboard.kde.org/r/5496 to allow having leading zeros when renaming files: E.g. Using the name "A ###.jpg" results in the filenames "A 001.jpg", "A 002.jpg"... The patch could be simplified a little bit by guaranting only one connective sequence of #'s.

- Move the renaming code into the RenameDialog
