Rename all .jpeg to .jpg, .htm to .html, .md to .txt, etc...

Select a folder, and it will replace all matching extensions to the desired one. All name collisions will be logged, so you can decide what name to use instead.

Warning: DO NOT remove the collision check (File Exists), otherwise you may lose files, because "File Move Block" replaces the destination file without errors or warnings.

`#d` uses 64b of memory but using `d` inside a "For Each" increases total memory usage by 1 order of magnitude (because the array is duped). Using `#d` is noticeably more efficient when "recursive mode" is enabled.
