Updated depreciated parts of node syntax

[tiloso]

Hi everyone,
I've updated depreciated parts of the syntax to eliminate occurring warnings.
The inserted links document the current syntax.

http.createClient => http.request:
http://nodejs.org/api/http.html#http_http_createclient_port_host

process.addListener => process.on:
http://nodejs.org/docs/v0.4.1/api/process.html#process

Please review the changes.

@tiloso Thanks for submitting, I'm going to get this tested before merging into the master.

@tiloso "depreciated" means something has lost value. "deprecated" means something has been obsoleted.
