Name typing breaks on import into Ontopoly

[GoogleCodeExporter]

If an existing topic map without an Ontopoly schema is imported into 
Ontopoly, all the topics are required to have a name of type http://
psi.ontopia.net/ontology/untyped-name, even if they already have names of 
type http://psi.topicmaps.org/iso13250/model/topic-name.

These two name types are of course equivalent, and should be treated as 
such. In fact, we should probably get rid of untyped-name in favour of 
tmdm:topic-name.
