WordPress/wp-includes/js/backbone.min.js
Andrew Nacin 07adb0640f Update Backbone from 1.0 to 1.1.
Also update Underscore to 1.6. Includes the development versions of both, which are not included in the build.

Here is Backbone's changelog:
 * Made the return values of Collection’s `set`, `add`, `remove`, and `reset` more useful. Instead of returning `this`, they now return the changed (added, removed or updated) model or list of 
models. (This means they can no longer be chained.)
 * Backbone Views no longer automatically attach options passed to the constructor as `this.options` and Backbone Models no longer attach `url` and `urlRoot` options, but you can do it yourself if you prefer. (But if you extend `wp.Backbone.View`, options will be attached for you.)
 * All `"invalid"` events now pass consistent arguments. First the model in question, then the error object, then options.
 * You are no longer permitted to change the id of your model during `parse`. Use `idAttribute` instead.
 * On the other hand, `parse` is now an excellent place to extract and vivify incoming nested JSON into associated submodels.

See [27171] (next commit) for changes made to WordPress to be compatible with Backbone 1.1.
