Now it creates a pidfile in /var/run on start and removes it on stop. This is useful in order to control the script with monit.
I have also changed the way to obtain the pid in order to kill the process and now it uses the name of the script itself, not the combination of node + webapp paths.

You have a dangling </pre> on line 67. Otherwise, I'm off to give this a spin! Thanks!

Why kill -9 on stop instead of kill -TERM? Kill -9 doesn't give the process a chance to clean up and shut down.
