Title: Add aliases for some functions

This mirrors the [Backbonejs events API](http://backbonejs.org/#Events) and to a lesser extent the
[Nodejs events API](http://nodejs.org/docs/latest/api/events.html#events_emitter_on_event_listener).

- `on()` = `addListener()`
- `off()` = `removeListener()`
- `trigger()` = `emitEvent()`

We use use EventEmitter in more places than Backbone, so it's nice to be able to use the same API between objects that mixin `Backbone.Events` and those that mixin `EventEmitter`.
