Fixing an issue with datamapper 0.9.1 where before :save throws an super: no superclass method `save' - (NoMethodError) error. Changed all before :saves to before :create and :update respectively, except for the article save_events, and moved include DataMapper::Resource to the bottom of the include list. I think that was the real fix.
