OBS: Migration needed(objects, scripts, players). This resolves issue 136 by allowing database objects to be nested in lists and dictionaries as
attributes on objects. Behind the scenes, only the DBREF is stored since storing dbobjects cannot be pickled. One used to be able to store single objects this way, but objects hidden in nested iterable structures were not found. Note that ONLY lists and dictionaries are supported to store on attributes - custom iterables will be stored and retrieved as a generic list instead - this is a tradeoff to be able to store database objects. To migrate, give the following commands from game/: migrate.py migrate objects migrate.py migrate scripts migrate.py migrate players
