Improve node-red startup log information

When I first installed and ran node-red two things slightly annoyed me.  First, I needed to manually install npm packages contained by the different nodes.  Second, I didn't have a way to easily copy and paste the public IP address of the Amazon EC2 server I was working on.

This pull request adds some terminal logging to the initial startup of node-red to fix the second annoyance and improve the first one (until such a time as nodes are npm installable directly).
