Title:  [#74] Removing button when no image on the question

Now, the detail of a session or a IQSet will only show buttons when there is a picture.
But we have a problem with the detail of a question. The parameter PICURL is not existing on detail-session (but the same thing on iqset-detail works). I have to check why this parameter is missing.
