- added a third layer of inheritance to polymorph test
- added some extra logic to mapper to try to convert a "foreign key" holding PK-col
into a non-FK col
- apparently, polymorphic loading can now be achieved with LEFT OUTER JOINs quite easily (i.e. no UNIONs).
this needs to be studied further (i.e. why was I making everyone use UNION ALL all this time)
