The manager that holds widgets is the WidgetManager

UIManager named the category, not the contents. Every other manager is
named after what it registers — ItemManager holds Items, SceneManager
holds Scenes — so the one that registers Widgets is the WidgetManager.

The alias, the Game field and both manual pages move together.
