Fixes several crashes and problems with backwards compatibility. Before expressions were allowed, field names were loaded and saved unquoted, e.g. x.y - with introduction of expressions it was necessary to use properly quoted "x.y" name so that expression is correctly parsed. With these changes both options are possible and when possible, the unquoted field name is used for compatibility
