belongs_to needs to be able to support polymorphism. #44

So that the same class can be used in multiple contexts and correctly address its owner.

[ ] Relatable::Metadata should have an attribute: polymorphic
[ ] Reference should disable lookup_reference if its metadata is polymorphic
[ ] Relation should set itself as the reference object on push / build, and unset on delete

Obvious caveat of this approach: not possible to look up a polymorphic reference without outside context.
