Active Model Observers Activation

Activates the observers assigned. Examples:

class ORM
  include ActiveModel::Observing
end

# Calls PersonObserver.instance
ORM.observers = :person_observer

# Calls Cacher.instance and GarbageCollector.instance
ORM.observers = :cacher, :garbage_collector

# Same as above, just using explicit class references
ORM.observers = Cacher, GarbageCollector

Note: Setting this does not instantiate the observers yet. instantiate_observers is called during startup, and before each development request.
