Remove draper patch for localization
Fix functional tests to cope with new collection decorator

Mostly this involves dereferencing the underlying collection from the decorator.
Remove draper from world org presenter
Provide a whitehall based class for decorators

We do this so we can extract some of the behaviour around delegating methods to the decorated class.  Turns out we need to make sure that any AR classes we are delegating to have been fully realised before we ask for their instance_methods, otherwise our delegation falls through to the default method_missing, which might pick up on attributes, but equally might not.
Add more methods to the list we delegate

Specifically all those helpful methods like .blank? etc that we get from rails.  Maybe we should just delegate everything we haven't specifically overridden ourselves.  That might be better?

Remove draper from PersonPresenter
