EDIT2: There you go. Added routine to close apps nicely if possible, and if not, kill them and logs out.

Here you go. A simple script you can setup to run automatically in the background using launchd or other means of your liking...

EDIT: Your question has already been answered really, it's just that your action, after idle time, is different. Take a look here at,
