Log:
Add machine->fieldchange relation

I've seen situations where fieldchange entries for a machine linger
around, even after removing all runs and their related fieldchange
entries.  Hopefully making the relation explicit and participate in the
sqlalchemy delete cascading makes things more reliable.
