Give access to the server

[lastmjs]

The use case I'm having trouble with is setting up socket.io. I do not have access to the server before it starts listening, and so I can't hook up socket.io correctly. What if we could pass in a function to be applied with the server before the serve starts listening in express-app?

I tested things out, and it looks like you can setup socket io after the server has started listening. So, just add the server as a parameter to the express-config callback, that should fix the issue.
