Better fix for -xf-hide-fields so that the QuickForm class doesn't need to change the global widget type for a field.  Now it just adds CSS to the head to hide the field's row.  Also the -xf-hide-fields parameter is passed to the resulting edit form after the new record form completes so that the fields stay hidden.
