We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_level_for_user_api_key site setting to user_api_key_allowed_groups. This isn't used by any of our plugins or themes, so very little fallout.
