Skip Applescript on MacOS

[MikeDacre]

The code works fine on Mac, but it is slow because applescript is slow, I think there should be a way to bypass applescript by editing the .DS_Store files, but I haven't bothered yet as there isn't good documentation on how this even works.

macOS ships with Python2.7 and PyObjC as standard. Use -[NSFileManager trashItemAtURL:resultingItemURL:error:].
