<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Customize: Add infrastructure for trashing/reverting of unpublished changes; introduce full-screen `OverlayNotification` for trashing and theme install/preview.

* Introduce a new `wp.customize.previewer.trash()` JS API to trash the current changeset, along with logic to `WP_Customize_Manager` to handle deleting changeset drafts.
* Add `trashing` to `wp.customize.state` which is then used to update the UI.
* UI for trashing is pending design feedback. One possibility is to add a new trash button to Publish Settings section that invokes `wp.customize.previewer.trash()`.
* Improve logic for managing the visibility and disabled states for publish buttons.
* Prevent attempting `requestChangesetUpdate` while processing and bump processing while doing `save`.
* Update `changeset_date` state only if sent in save response.
* Merge `ThemesSection#loadThemePreview()` into `ThemesPanel#loadThemePreview()`.
* Remove unused `autosaved` state.
* Start autosaving and prompting at beforeunload after a change first happens. This is key for theme previews since even if a user did not make any changes, there were still dirty settings which would get stored in an auto-draft unexpectedly.
* Allow `Notification` to accept additional `classes` to be added to `container`.
* Introduce `OverlayNotification` and use for theme installing, previewing, and trashing. Such overlay notifications take over the entire window.
