Added that Active Records will automatically record creation and/or update timestamps of database objects if fields of the names created_at/created_on or updated_at/updated_on are present. [Tobias Luetke] Added acts_as_tree that can decorates an existing class with a many to many relationship with itself. Added acts_as_list that can decorates an existing class with methods like move_higher/lower, move_to_top/bottom.
