Adding stoptimeout and stopparentfirst for clean shutdown support

[hockeytim11]

This is a followon from the node-windows pull request.

I have not really tested the debian systemv path yet. I will probably get to that on Monday. But it is a really small change using the existing daemon script so I thought I would get this started.

The stopparentfirst argument doesn't seem applicable to the systemv path, as that is the default behavior.
