Knockout input value trimming on edit

Ember input value trimming and text selection removal

Backbone input value trimming on edit

 - 2x: The unminified version contains invariants that shouldn't be used in production and slow it down.

 - 3x: Adding a shouldComponentUpdate override in order to short-cut re-rendering the component when props and state didn't change. In order to do that, we need to avoid doing mutations by doing a shallow copy and only modifying what changed

 - When React 0.5.0 will be released, it will give another 1.5x.

Other miscellaneous changes:

 - Update class="..." to className="..." to work in 0.5.0 (still works in 0.4.1)
 - Use prop="..." instead of prop='...'
 - Use filter(f, this) instead of filter(f.bind(this)) to prevent a function allocaton
