Attach an EventEmitter listener that emits before all other existing listeners
for that event.

Note: it's also worth checking out [timoxley](http://github.com/timoxley)'s
[overshadow-listeners](http://github.com/timoxley/overshadow-listeners/). The
API offers more flexibility, and unlike `on-first` only uses the public
EventEmitter API.
