\keypubs is broken in euproposal.pdf

[kohlhase]

We are using the bibLaTeX category system for generating these. This works well for dfgproposal.cls which has only one of these. But here we get the same publications for every site, since they are only featured. We should at least give a keyword or category per site and add that to the publications. It would probably be good to also add the category (or use; are categories exclusive?) keypubs. Then we can remove them from the regular publications.

Maybe it is better to use a key keypubs in for the {sitedescription} as an interface. Then we can only use it there.
