Facilities for treating large numbers of authors

Needed: a way to (semi-)automatically create Profiles/affiliations from a TeX list of authors.

Idea:

• first have a formset to select a number of Organizations listed as affiliations, with an identifying token to be matched in the TeX snippet
• then a textarea where the list of authors with tokens can be pasted. Processing then gives a list of matching Profiles and news instances.

While UnregisteredAuthor is still used, might have to go through this.

Should the corresponding author be asked to do this?
