Adding access to HTTP server for server.js

I'm trying to write a little test app that uses socket.io and want to prototype
the backend with all of the niceties that lineman gives for free. This small
change enables that without breaking any backward compatibility.
Merge branch 'modify_http_server_clean' of github.com:tonyarkles/lineman into tonyarkles-modify_http_server_clean
now with 75% more existential operator. ?!
