'Show Desktop' Applet For Docky (Gnome-Do)

docky show desktop

I know a lot of you are using Gnome Do for quite some time, but I've only recently switched to it. One of the most annoying things when running it in Docky mode (Dock bar) is that it doesn't have to many applets, and I can live with that but now without a "Show Desktop" shortcut.

Yes, you can use a keyboard shortcut for showing the desktop, but I wanted this in Gnome Do / Docky and managed to create an applet (actually a script) to use in Docky.
