[gen] Added attribute 'xml' on every field allowing to customize the XML marshalling process. [gen] Added new layout 'xml', now different from the 'view' layout, allowing to define which fields are to be dumped in the XML version of some object. [gen] Security fix in ToolMixin::getUser. [gen] Bugfix in Mixin::getUrl. [shared] dav.py: method 'get' can now accept parameters. [shared] xml_parser: changes to the XmlMarshaller (due to XML-related changes).
