Windows installation enhancement

[danyhm]

hello again!

thanks for the windows tutorial. I installed it on my server and it worked. however, there are 2 issues that would make it even better.

1- Add autostart feature. 2- install as a service so it runs even if the user doesn't log in. this way those 2 annoying node command prompts will go away as well.

some people suggest using nssm but I know pm has windows service and startup feature.
