Since the observer system now uses shared_ptr and many registrations are done in the constructors, and since we cannot called shared_from_this() in the constructors, it is mandatory to split construction from registration. This has been done by making many ctors protected and replacing them by factory methods that directly return shared_ptrs + added PostConstructor method when base classes perform shared_from_this() calls too.
