[josm-dev] add relicensing problems to search options

[Jo]

Hi,

While wasting inordinate amounts of time trying to resolve license
issues, I found it would be handy to be able to search for objects
that are in the list shown in the Relicensing problem tab.

I 'd also like to be able to exclude nodes that are part of junctions
automatically. I think it's already possible to search for nodes which
have tags.
