- Removed ancient assertion that mapped selectables require
"alias names" - the mapper creates its own alias now if
none is present. Though in this case you need to use the

- added a feature to eager loading whereby subqueries set
as column_property() with explicit label names (which is not
necessary, btw) will have the label anonymized when
the instance is part of the eager join, to prevent
conflicts with a subquery or column of the same name
