Subject: [PATCH] add an optional property node pointer to ObjectProperty. This
 is currently only used by the <list> widget. It allows to "dialog-update" the
 list, which rescans the <value> children and redraws the list widget with new
 contents. The old contents are only freed at dialog close, which should
 eventually get changed.
