EventEmitter = process.EventEmitter is no longert valid for Node > 6.x

[hawkeye64]

My approach to fixing this does not break any backwards compatibility for Node < 6.x. I have incorporated the "semver" library to determine if the version of Node being used should be one way or the other for event emitters.

Node < 6.x:
var EventEmitter = process.EventEmitter

Node >= 6.0.0
var EventEmitter = require('events')

I am using this in production.

If someone can tell me why Travis is failing on the "semver", it'd be appreciated.

@hawkeye64 Looks like a very old node version in Travis config. Issue with old npm version may be to blame.
From the Travis log:

$ node --version
v0.8.28
$ npm --version
1.2.30
