Log Message:
-----------
Add read-only property to check if any duplis are used. Without this, ob.create_dupli_list(scene) crashes when no duplis are on the object. We cannot use  duply_type !='NONE' because for non rna dupli types like dupli_particles, it fails. And some dupli types, we don't want to have in rna
