this way journal classes are only created for classes with
calls to acts_as_journalized. You may now subclass journaled models to extend them with helper methods in plugins w/o interfering with aaj.

Taken from Redmine r5880

This will allow the Journaled object to reliability set the fields on the Journal
without calling init_journal (which is a before_save hook and shouldn't be called
directly).

Some models (Changeset) require custom options passed to
acts_as_activity_provider but acts_as_journalized wasn't accepting these
for :timestamp or :author_key

This will let them pick up the committer string if user is nil

So the initial journal would have the changes from an Object#new
to the created version of the Object. Also includes a change to the
database migration in order to create these initial journals for
all journaled Objects.

In one case in a plugin (not able to reproduce in core) journal_attributes_for_user
would set the :user to something different than what's in updated_by thus assigning
the Journal to the wrong user.

acts_as_journalized called changes as per ActiveRecord::Dirty 
(see http://ar.rubyonrails.org/classes/ActiveRecord/Dirty.html#M000291), 
the journalized model Changeset :has_many changes though, which 
made the call return a list of associated objects instead of the 
intended list of changed attributes. Replaced changes with the code
from AR::Dirty to work around that.

This problem occurs because the EOF character string is included in the built-in font.
