They can be bundled. Just the git repos can't. Use rails/rack-mount for that.

This reverts commit ef6cdc97.

Instead of using a single `notify_observers` call for every callback type,
each observer now registers a unique callback for itself. Example:

  before_save :_notify_user_observer_for_before_save

  def _notify_user_observer_for_before_save
    observer.update(:before_save, self)
  end

Benefit: "before" callbacks halt when `observer.update` returns false.
This way, ActiveRecord observers can prevent records from saving.

`Observable#notify_observers` from Ruby always returns false (which halts ActiveRecord
callback chains) and has extra features (like `changed`) that were never used.

Benefits: test able to run independently, subclassing instead of changing the original Comment model
