[PATCH] Restore changed_attributes method in ActiveModel::Dirty

Reported by Sam Pohlenz | April 1st, 2010 @ 12:01 PM | in 3.0.2

It seems that this commit removed the changed_attributes method from ActiveModel::Dirty, which lazily loaded the @changed_attributes ivar.

This then required another commit to ensure that the necessary ivars are initialized. However this still has the major drawback of requiring the including class to call super in its initialize method (depending on the inclusion order). This should not be necessary.

This patch restores the changed_attributes method. It is simpler, it uses a common pattern and removes these specific undocumented requirements on the including code.
