ChangeScreen2: Show rename/copy source paths in file table

Display below a renamed or copied file the source path the file
came from. This is displayed in one font size smaller than the new
path text, and using the lighter grey that is used for common path
prefixes. The idea is to make the information available, but the
old path is usually less important, and should therefore be less
obvious in the UI.
