Config delegation & reload improvements

Browse source 
- Added a class and an interface to make using list config data easier
- Made everything config-related reusable and reloadable because delegated properties don't update automatically when reassigned
- This also means that the original ConfigData instance should also properly update now when reloading, although now we return the delegate
