Idea: automatically bind observers and event handlers

[rstacruz]

I've been working on an Ractive app, and this pattern of automatically adding event hadlers and observers is very pervasive:

module.exports = Ractive.extend({
  init: function () {
    this.on(this.eventHandlers);
    this.observe(this.observers);
  },

  eventHandlers: {
    'submit': function () { ... }
  },

  observers: {
    'quantity': function () { ... }
  }
});

...it'd be nice to be able to bind these automatically.

Totally get where you're coming from - this was actually discussed this in a previous issue. But it turns out to be a bit more complicated than it first looks - I dug into it a bit a while back and realised that it creates a lot of problems. I jotted down some of my thoughts here.

Awesome. Closing this now as a dupe of #360 and #405. Thanks for your consideration!
