Wolfy87/EventEmitter — Issue #24: off alias just like on alias

quite a few js libraries that have binding and unbinding of events seem to be adding the on/off aliases for the respective events.

even though I have this in my own implementation, I think it would be handy to have this in the library:

```javascript
EventEmitter.prototype.on = EventEmitter.prototype.addListener; // this is there
EventEmitter.prototype.off = EventEmitter.prototype.removeListener; // this isn't
```
