* Correct several incorrect uses of `_.union`. Since Underscore 1.7.0 `_.union` supports only arrays and not variadic args.
* Use a namespaced event `themes:update`. Backbone 1.2 added a built in `update` event that triggers after any amount of models are added or removed from a collection.

Backbone, from 1.1.2 to 1.2.3. Underscore, from 1.6.0 to 1.8.3.
The new versions of Backbone and Underscore offer numerous small bug fixes and some optimizations and other improvements. Check the [http://backbonejs.org/#changelog Backbone changelog] and [http://underscorejs.org/#changelog Underscore changelog] for the full details.
The new versions include some significant changes that may break existing code. Plugins or themes that rely on the bundled Backbone and/or Underscore libraries should carefully check functionality with the latest versions and run any available unit tests to ensure compatibility.
Some changes of note that were addressed in core as part of this upgrade:
* `_.flatten` no longer works with objects since Underscore.js 1.7. `_.flatten()` working with objects was an unintended side-affect of the implementation, see [https://github.com/jashkenas/underscore/issues/1904#issuecomment-60241576 underscore#1904]. Check any `_flatten` usage and only flatten arrays.
* As of Backbone 1.2.0, you can no longer modify the `events` hash or your view's `el` property in `initialize`, so don't try to modify them there.
* Since Underscore 1.7, Underscore templates no longer accept an initial data object. `_.template` always returns a function now so make sure you use it that way.

In the Edit Menu screen, each menu item creates 11 form input elements. In menus with more than 71 menu items, often items after the 71st weren't saved. This was because PHP's runtime configuration `max_input_vars` default value is 1000. Large menus exceed this, so PHP didn't populate the `$_POST` superglobal for the latter menu items.
The entire form is now JSON-encoded into a single input which populates `$_POST` manually on form submission.
This was attempted previously in [36506] which was reverted in [36507]. Some form fields were not being slurped into the form's JSON representation, and it did not scale for a site with many posts. This approach fixes those problems.

* Export nonces centrally in `wp.customize.settings.nonce` with each request and update nav menus preview to utilize.
* Send updated nonces to preview upon `nonce-refresh`.
* Request full preview refresh if Nav Menu selective refresh request fails (e.g. due to bad nonce).
* Update nav menus and widgets in Customizer to utilize `customize_refresh_nonces` for exporting nonces and keeping them up to date.

* Upon `saved` event, send `saved` message to preview with the `response` to trigger `saved` event there.

* Continue to create settings synced from pane even after initial bootstrap, and create them as dirty.

When sorting a metabox, a clone of that metabox is created as a drag/drop "helper".
Previously, any checked radio input in the original metabox would become unchecked, when its clone "helper" was inserted into the DOM
(since only one radio within a set of radios of the same name can be checked).
Continued use of the clone helper is important so that the element being dragged isn't subject to the click and other event handlers attached to the real metabox,
so we can't just switch to dragging around the real metabox. See, for example, comment:10:ticket:16972.
Preserve the radios' state via some name attribute trickery.

This issue would appear when the parent nav menu item was also newly-inserted. The issue was only apparent in the prevew, as the actual data saved was correct. The `menu_item_parent` properties of the saved sub-nav menu items needed to get updated to refer to the newly-inserted parent `nav_menu_item` post IDs, as opposed to retaining the placeholder IDs.
