Listen to multiple ports

[subnetmarco]

For example a server application listens to both HTTP (port 80) and HTTPS (port 443), to handle both protocols in the same node process.

this will be a lot easier with node 0.6.x cluster stuff, +1 this if you're interested nodejs/node-v0.x-archive#1879
if accepted I'll be migrating the functionality of learnboost/cluster as plugins for the new core cluster stuff
