Well it's quite easy to just special case every class that starts with 
KTextEditor::, and that's all we need to do. We don't need to instantiate 
KTextEditor classes with new, but CreateInstance has to be able to work.

I changed the smoke code generation so that you can now call pure virtual 
methods. I don't think we should get rid of abstract methods as mostly they 
are actually abstract and we would be losing some meaning from the original 
C++ api. If there are other places where pure virtual methods are being used 
as interfaces like in KTextEditor we can always special case them too, but I 
don't know of any others - maybe KDevelop does that, but I haven't looked 
much yet.
