Adding declarative bindings for Controllers, Models, Collections, and CollectionViews

[albatrocity]

delegateListeners and delegateListener have been moved to the EventBroker so that all classes that mix it in can define a listen object to define event listeners. The delegateListeners method is called in the constructor of Views, Models, Collections, and Controllers. Basically applying #419 to the other basic Chaplin classes.

The motivation behind this was so I could do:

class ThingController extends Controller
  listen:
    'saveThing mediator': 'update'

  update: (model) ->
    model.save
      success: =>
        @redirectTo 'things'

instead of:

class ThingController extends Controller
  initialize: ->
    super
    @subscribeTo 'saveThing', @update

  update: (model) ->
    model.save
      success: =>
        @redirectTo 'things'

I do this a lot and overriding initialize was starting to feel dirty 😄

Oh, it's cool! Let's be more declarative.
