Subject: Python: Be more consistent with other container objects and classes

This enables testing whether a key exists in an object (e.g. "'title'
in track") as well as iterating over a Track or Photo object's keys,
values, or items.  The items() and pairs() methods were renamed to
values() and items(), respectively, in the Track and Photo classes.
