Move names into attributes

Issue description

This reduces the need for name types. All name types become occurrence/attribute types.

Developer comments

Not sure about this one, because this would be quite difficult for the following reasons: * The existing name items have an id which collides with an id in the occurrences. * Names are attributes that are used by humans for referral to the topic. This makes a lot of sense.

Rejection comment

Yes, one table is better than two but there is conceptually quite a big difference so it remains as is for now.
