New `Server.listen(options[, callback])` method is too picky about port being a js number

[brycebaril]

Really like this new new listen function, but I've found it's pickier than the others about port being a js number vs a string number, and the error is unclear (uses poor stringification of the object):

// Old .listen(port[, host][, callback])
http.createServer(function (req, res) {
  res.end("\n")
}).listen("8005")

Works fine, converting "8005" to 8005.

While:

// New .listen(options[, callback])
http.createServer(function (req, res) {
  res.end("\n")
}).listen({port: "8005"})

Throws:

Error: Invalid listen argument: [object Object]
