* Customization locking is checked when changesets are saved and when heartbeat ticks.
* Lock is lifted immediately upon a user closing the Customizer.
* Heartbeat is introduced into Customizer.
* Changes made to user after it was locked by another user are stored as an autosave revision for restoration.
* Lock notification displays link to preview the other user's changes on the frontend.
* A user loading a locked Customizer changeset will be presented with an option to take over.
* Autosave revisions attached to a published changeset are converted into auto-drafts so that they will be presented to users for restoration.
* Focus constraining is improved in overlay notifications.
* Escape key is stopped from propagating in overlay notifications, and it dismisses dismissible overlay notifications.
* Introduces `changesetLocked` state which is used to disable the Save button and suppress the AYS dialog when leaving the Customizer.
* Fixes bug where users could be presented with each other's autosave revisions.

Improve JS parsing of our inline JSDocs by introducing `@namespace`, `@lends` and `@memberOf`. Helps set the way for showing our JavaScript documentation on developer.wordpress.org, see https://meta.trac.wordpress.org/ticket/3063.
* Define all used namespaces using @namespace.
* Correctly specify in which namespace each class is using @memberOf.
* Define each usage of the extend function as a prototype assignment using @lends.
* Some comment blocks were moved to correct the parsing of certain definitions.

- Use the page visibility API (when available) and document.hasFocus() instead of window.onfocus/onblur. Improves speeding up/slowing down the interval and works for iframes by default.
- Add a setting for minimal interval. Maximum value is 10 min. This overrides all other intervals and cannot be changed after setting it at initialization. Can be used to reduce the frequency of requests on hosts that have low limits for used CPU time, etc.
- Extend the setting of interval to support 120 sec. (60 sec, is still the default).
- Always suspend after one hour of keyboard/mouse/touch inactivity.

- Speeding up heartbeat: bring back the setting how long it should last (how many ticks).
- Add 'heartbeat-nonces-expired' jQuery event when nonces have expired and the user is logged in.
