Unquarantien downloaded files on macos with an applescript droplet

unquarantine.scpt

(*
loosely based on "Unquarantine" by Henrik Nyh <http://henrik.nyh.se/2007/10/lift-the-leopard-download-quarantine>
This Folder Action handler is triggered whenever items are added to the attached folder.
It gets rid of Leopard's annoying "this application was downloaded from the Internet" warnings by stripping the "quarantine" property.

Now also runs as a droplet or a standalone application if, like me, you juste need sometimes to stop the madenning dialog to appear for every file of a downloaded (unzipped) zip archive.
