Obsolete SettingsHolder.Set<T>(Action value) overloads

[timbussmann]

This overload saves the action under the fullname of T but it doesn't act like a factory or something, so it's equal to Set(typeof(T).FullName, action) and you can't do a Get<T>() as that would try to cast the action to T which would most likely fail. The only way to retrieve the action again is via Get<Action>(key).

I can't come up with any reasonable use case for this API?
