[Dbix-class] Rows as singletons

[David Cantrell]

I've been mumbling on IRC over the last week or two about rows being
singletons when they get loaded into memory.  This is mostly because,
when writing tests for a DBIx::Class based project I got irritated when
I had two references to the same row hanging around in memory, update()d
one of them, but the other still had old data in it.

Here's my fix:

Comments would be most welcome.

Please note that it shouldn't be re-distributed yet, or used in any of
your projects, as it's not yet got a proper licence on it.

shoes, bathe and not make messes in the house.
