Config needs to handle versioning and moderation too

[jonathan-s]

The url manager has an option of using djangocms-navigation. As djangocms-navigation also supports versioning and moderation the url manager should be able to handle these options as well.

Currently the pattern seems to be DJANGOCMS_NAVIGATION_CMS_MODELS_ENABLED since this relates to the url manager I think it would be more appropriate to have the setting to be DJANGOCMS_URL_MANAGER_NAVIGATION_ENABLED.

The same would go for versioning moderation.
