[bioontology-support] Obsolete terms showing and not indicated as obsolete

That's a very good point and handling obsolete terms is on our list of  
things to do. Part of the problem is that we need to find a solution  
that will work for all formats, not just OBO, and OWL, for example,  
doesn't have a standard way to handle obsolete terms, We have a decent  
idea on how to do this, but we haven't gotten around to implementing  
it yet.
