Open Terminator from nautilus context menu

On our Ubuntu machines we have nautilus file manager with nautilus-extension-gnome-terminal installed. This adds an entry to the context menu (right click) to start a gnome-terminal in the current directory. As I'm mostly using Terminator terminal, I wanted to have a similar context menu entry to launch Terminator directly. I came across this python script Show archive.org snapshot that does exactly that.
