Description

Cayenne uses expression like src.id = dst.fk as a join clause and this is hardcoded for now.
We can extend this to accept any Expression.
This will require redesign in Modeler DbJoin creation dialog and some changes in SelectTranslator. Also this may touch some logic that depends on DbRelationship.isSourceIndependentFromTargetChange() method.
