Done on the same branch. Nothing fancy was needed in the other Entity
subclasses.

NB: It looks like Entity supports some methods that are handled just as well by
the appropriate magic methods and Python syntax: get_list => __iter__,
detach_child => __delitem__, has_id => __contains__. We should eventually
deprecate those methods, make some others non-public, and promote the use of
properties and magic syntax instead, I think.
