Removes automatic registration of settings

Browse Source 
Original intention was to register Settings automatically for DI. This ran into problem when the container verifies the configuration is valid for a settings using the constructor for initialization. It tries to resolve the parameters and fails.

This removes the automatic registration and falls back ActivatorCreateInstance when no Setting is registered.
