[Meta] 2.x release

Full upgrade from 1.1 to 2.x-dev completed. 10,000 reviews were migrated. Configuration updated. Views imported. Works without needing a cache rebuild.

Things missed to be fixed before release:

• Update hook that imports configuration missing mention of product review page view.
• Admin view published filter options are still true/false and need the labels for the options configured.
• Admin view items per page needs to be bumped up to 20.
• Number of reviews per page on customer's account reviews tab is excessive.

Needs a code review of changes from 1.x

Documenting breaking changes:

• HTML structure of overall rating field has changed. Container elements have been added along with classes to make styling easier.
• Theme suggestions for product review entity have been fixed so any custom templates created that weren't working before might take effect after upgrading.
• Admin review list page has been replaced by a view. Ensure you have Drupal Core's view module enabled before upgrading.
• The page of reviews on a product has had a view created for it. The view will respect your existing template for the review entity. The view can be safely disabled if you do not want the additional features added by the view.
• Customers now have the ability to edit and delete their own reviews if granted permission. Review your configured module permissions to enable these features.
