Fixed bug #863 : Data submission fails on Safari browser. Was due to Safari not handling onchange event on radio buttons, thus I added a manual modfield in checkconditions for this browser. This contains also a fix for not adding hidden input fields for previous answers if conditions are not set, and to avoid having duplicate javaXXX hidden fields as it was the case
