Customize: Extend changesets to support autosave revisions with restoration notifications, and introduce a new default linear history mode for saved changesets (with a filter for opt-in to changeset branching). * Autosaved changes made on top of `auto-draft` changesets get written on top of the `auto-draft` itself, similar to how autosaves for posts will overwrite post drafts. * Autosaved changes made to saved changesets (e.g. `draft`, `future`) will be placed into an autosave revision for that changeset and that user. * Opening the Customizer will now prompt the user to restore their most recent auto-draft changeset; if notification is dismissed or ignored then the auto-draft will be marked as dismissed and will not be prompted to user in a notification again. * Customizer will no longer automatically supply the `changeset_uuid` param in the `customize.php` URL when branching changesets are not active. * If user closes Customizer explicitly via clicking on X link, then autosave auto-draft/autosave will be dismissed so as to not be prompted again. * If there is a changeset already saved as a `draft` or `future` (UI is forthcoming) then this changeset will now be autoloaded for the user to keep making additional changes. This is the linear model for changesets. * To restore the previous behavior of the Customizer where each session started a new changeset, regardless of whether or not there was an existing changeset saved, there is now a `customize_changeset_branching` hook which can be filtered to return `true`. * `wp.customize.requestChangesetUpdate()` now supports a second with options including `autosave`, `title`, and `date`. * The window `blur` event for `customize.php` has been replaced with a `visibilitychange` event to reduce autosave requests when clicking into preview window. * Adds `autosaved` and `branching` args to `WP_Customize_Manager`. * The `changeset_uuid` param for `WP_Customize_Manager` is extended to recognize a `false` value which causes the Customizer to defer identifying the UUID until `after_setup_theme` in the new `WP_Customize_Manager::establish_loaded_changeset()` method. * A new `customize_autosaved` query parameter can now be supplied which is passed into the `autosaved` arg in `WP_Customize_Manager`; this option is an opt-in to source data from the autosave revision, allowing a user to restore autosaved changes.

Customize: Extend changesets to support autosave revisions with restoration notifications, and introduce a new default linear history mode for saved changesets (with a filter for opt-in to changeset branching). * Autosaved changes made on top of `auto-draft` changesets get written on top of the `auto-draft` itself, similar to how autosaves for posts will overwrite post drafts. * Autosaved changes made to saved changesets (e.g. `draft`, `future`) will be placed into an autosave revision for that changeset and that user. * Opening the Customizer will now prompt the user to restore their most recent auto-draft changeset; if notification is dismissed or ignored then the auto-draft will be marked as dismissed and will not be prompted to user in a notification again. * Customizer will no longer automatically supply the `changeset_uuid` param in the `customize.php` URL when branching changesets are not active. * If user closes Customizer explicitly via clicking on X link, then autosave auto-draft/autosave will be dismissed so as to not be prompted again. * If there is a changeset already saved as a `draft` or `future` (UI is forthcoming) then this changeset will now be autoloaded for the user to keep making additional changes. This is the linear model for changesets. * To restore the previous behavior of the Customizer where each session started a new changeset, regardless of whether or not there was an existing changeset saved, there is now a `customize_changeset_branching` hook which can be filtered to return `true`. * `wp.customize.requestChangesetUpdate()` now supports a second with options including `autosave`, `title`, and `date`. * The window `blur` event for `customize.php` has been replaced with a `visibilitychange` event to reduce autosave requests when clicking into preview window. * Adds `autosaved` and `branching` args to `WP_Customize_Manager`. * The `changeset_uuid` param for `WP_Customize_Manager` is extended to recognize a `false` value which causes the Customizer to defer identifying the UUID until `after_setup_theme` in the new `WP_Customize_Manager::establish_loaded_changeset()` method. * A new `customize_autosaved` query parameter can now be supplied which is passed into the `autosaved` arg in `WP_Customize_Manager`; this option is an opt-in to source data from the autosave revision, allowing a user to restore autosaved changes.

Customize: Introduce custom CSS for extending theme styles. * Custom CSS is associated with a given theme and is displayed in an inline `style` element at the `wp_head` hook after the `wp_print_styles` is called so that it overrides any enqueued stylesheets. * A `wp_get_custom_css()` function is used for accessing the CSS associated with the current theme (or another theme) and a `wp_get_custom_css` filter for manipulating it. * CSS is managed in customizer via a new "Additional CSS" section with a single `textarea` control. * `WP_Customize_Section::$description_hidden` is introduced for hiding extended descriptions in customizer sections behind a help toggle as done with panels. * CSS is stored in a `custom_css` post type with the theme (stylesheet) slug as the `post_name`. * `WP_Customize_Custom_CSS_Setting` is introduced to handle validation of CSS, previewing, and persisting the CSS to the `custom_css` post type. * The `custom_css` setting is tied to a new `unfiltered_css` capability which maps to `unfiltered_html` by default. * Escaping the message in the notification template is removed to allow markup (`code` tags) to be rendered.
