When accessing the Customizer from the admin menu, make sure the user is returned to the originating page upon close. We should still investigate the general usage of `customize-loader.js` moving forward, but this approach fixes the immediate issue. props westonruter. fixes #25457.

Allow an `array()` to be passed as the value for `orderby` to `WP_Query`. Allows for an independent `order` value for each key.

Example: `'orderby' => array( 'title' => 'DESC', 'menu_order' => 'ASC' )`.

Adds docs and unit tests.

When setting the poster image for a video shortcode, set that image as the featured image for that attachment (if found) in the background. This AJAX functionality could be used for audio as well.

Introduces `attachment_url_to_postid()` to attempt to turn URLs into post IDs.

More consistent icons in place of some buttons for the Customizer and theme install preview.

* Use a single close icon instead of a context-changing cancel/close button in the Customizer. In user testing, this small distinction in language was overlooked, and we use an AYS now instead. This also makes it consistent with the back arrow in Customizer panels.
* Use the same close icon as well as the previous/next arrows from the theme details browser in the theme install preview.
