Update to Node.js 8 events API

[cedx]

Let's try again! @defunctzombie, @connor4312, I don't want this package to be abandoned :)

This PR fixes issue #29. As for the PR #32, the code was copied from Node.js source and adapted:

• removed references to domain and process
• replaced ES template strings by concatenation
• replaced const statements by var ones

@cedx I no longer have time to maintain this package. I'd ping @Gozala and see if they will make you a maintainer.

Anyone knows how to fix the zull error raised by the unit tests?

Zuul tried to run tests in saucelabs, however no saucelabs credentials were provided.

@defunctzombie Thanks, it would be a pleasure to help maintaining this project.

[cedx]

@Gozala Do you still maintain this project? Or should we switch to another package like eventemitter3?

[Gozala]

@cedx @defunctzombie has being maintaining it for quite some time now, but it looks like he's no longer able. I'm happy to let you take over since @defunctzombie seems to be onboard with that as well.

[Gozala]

@cedx I just have added you to the collaborators list, if you'll tell me your npm name I'll add you there as well.

hey, i'm very interested in getting this in--any way i can help out?

[Gozala]

@goto-bus-stop wanna take over this pull so it actually passes test ?

[goto-bus-stop]

@Gozala I think the test failure is because this is a PR, and travis doesn't expose the SauceLabs authentication keys to PR builds (only branch builds). the tests themselves pass, but CI can't talk to saucelabs. it should turn green after merge

It seems like this is still failing on IE 8/9. Sadly I don't have no time to put into this if someone want's to fix help maintain this project comment on #43
