Theme support for `customize-selective-refresh-widgets` can be added _after_ the logic for registering the settings for incoming widgets that have been changed. This is due to themes adding the theme support in `after_setup_theme` which is also the action where `WP_Customize_Widgets::register_settings()` is called. If these both happen at priority 10, which one is called first depends on which one was added first. The other issue is that at the time that `WP_Customize_Widgets::register_settings()` is called at `after_setup_theme`, it is called before `widgets_init` and thus no widgets are yet registered. This means that any settings registered at this point will always have a `refresh` transport even if the theme supports `customize-selective-refresh-widgets`, since the `WP_Widget` instance is not visible yet to see if it supports selective refresh.
The fix: Defer `WP_Customize_Widgets::register_settings()` from `after_setup_theme` to `widgets_init` at priority 95 when the widget objects have all been registered. Also, ensure that the preview filter for `sidebars_widgets` is added before the sidebars are iterated for adding the controls.
Props westonruter.

* Implement and improve Masronry sidebar refresh logic in Twenty Thirteen and Twenty Fourteen, including preservation of initial widget position after refresh.
* Re-initialize ME.js when refreshing `Twenty_Fourteen_Ephemera_Widget`.

* Improves parity between partials and controls. A partial or control can be settingless if instantiated with `settings` param as empty array (otherwise, if null, then the partial/control ID is used).
* Eliminate need to create dummy settings that serve no purpose except to place a control in the UI.
* Removes dummy settings for `create_new_menu` and `new_menu_name`.
* Introduces `WP_Customize_Control::$capability` and `WP_Customize_Partial::$capability`, and if set checks them in the respective `check_capabilities()` methods.
* Prevents PHP fatal error from happening when non-existing settings are provided to control: "Call to a member function `check_capabilities()` on a non-object".
* Fixes issue where nav menu items and widgets were no longer working with selective refresh because cap check was failing.

* 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.

* Clear the `preview_applied` flag for aggregated multidimensional settings when a post value is set. This ensures the new value is used instead of a previously-cached previewed value.
* Move `$is_preview` property from subclasses to `WP_Customize_Setting` parent class.
* Deferred preview: Ensure that when `preview()` short-circuits due to not being applicable that it will be called again later when the post value is set.
* Populate post value for updated-widget with the (unsanitized) JS-value in `WP_Customize_Widgets::call_widget_update()` so that value will be properly sanitized when accessed in `WP_Customize_Manager::post_value()`.

Widgets panel will not wait to display until the preview loads.
Also fixes problems with `margin-top` in panels where other panels' `active` states change, as well as ensuring sections of deactivated panel collapse before panel is hidden to prevent the pane from becoming empty of controls.

The Menu Customizer feature includes a performance technique whereby the controls for nav menu items are only embedded into the DOM once the containing menu section is expanded. This commit implements the same DOM deferral for widgets but goes a step further than just embedding the controls once the widget area's Customizer section is expanded: it also defers the embedding of the widget control's form until the widget is expanded, at which point the `widget-added` event also fires to allow any additional widget initialization to be done. The deferred DOM embedding can speed up initial load time by 10x or more. This DOM deferral also yields a reduction in overall memory usage in the browser process.
Includes changes to `wp_widget_control()` to facilitate separating out the widget form from the surrounding accordion container; also includes unit tests for this previously-untested function. Also included are initial QUnit tests (finally) for widgets in the Customizer.

* Ensure that a Custom Menu widget selecting a newly-inserted menu gets updated to use the new menu ID upon Save & Publish.
* Dynamically update the visibility of the Custom Menu widget's "no menus" message when the number of menus changes between 0 and 1+.
* Send all dirty Customized settings in `update-widget` Ajax request and `preview()` them so that the widget update/form callbacks have access to any data dependencies in the current Customizer session (such as newly created unsaved menus).
* Update link in Custom Menu widget to point to Menus panel as opposed to Menus admin page, when in the Customizer.
* Fix an issue with extra space at top immediately after creating new menu.
* Fix doubled `update-widget` Ajax requests when changing select dropdown; prevent initial from being aborted.
* Add missing `wp_get_nav_menus()` hooks to preview Customizer updates/inserts for `nav_menu` settings; includes tests.
* Update `wp_get_nav_menu_object()` to allow a menu object to be passed in (and thus passed through).

This was broken since 4.0 and the introduction of user session tokens. The nonces are now tied to session tokens as opposed to user IDs, and thus they change with each re-login.
Custom nonces can be added through the `customize_refresh_nonces` filter. On a successful refresh request the JavaScript API will trigger a `nonce-refresh` event. See widget's update nonce as an example.

Create a panel via `$GLOBALS['wp_customize']->add_panel( $panel_id, $args )` and use `$panel_id` for the `panel` argument in `$GLOBALS['wp_customize']->add_section( $section_id, $args )`. That's it.
As an example all widget area sections are now summarized into one panel. Feedback appreciated.
