- several ORM attributes have been removed or made private:

mapper.get_attr_by_column(), mapper.set_attr_by_column(),
mapper.pks_by_table, mapper.cascade_callable(),
MapperProperty.cascade_callable(), mapper.canload()
- refinements to mapper PK/table column organization, session cascading,
some naming convention work
