Bind models and views using Backbone.stickit

[trabianmatt]

Backbone.stitckit is a library for binding models to views:

class SampleView extends Backbone.View

  # Any time the `name` attribute of @model is updated, the text of the element matching .name will be updated as well.
  bindings:
    '.name': 'name'

It would be helpful to have this integrated with titanium-backbone.

Simple one-way (model to view) binding on Labels and Buttons is working. Next up is text fields and other editable fields:

Add two-way support for editors:

• TextField
• TextAreas
• Switch
• SearchBar
• Slider
• Picker (may create a separate issue for this since we haven't provided a good abstraction for Pickers yet)

I posted a couple of related pull requests to backbone.stickit:

nytimes/backbone.stickit#54
nytimes/backbone.stickit#55

Hopefully we can get some form of those merged into master so we don't have to maintain a separate fork.
