Instances of F can now be compared for equality if their paths match and
provide a reasonable repr.
The changes to UpdateExpression included here are because implementing
eq for F means that setting the same field twice in an update
expresssion would ignore one of the values. This changes the behaviour
of F("a").set("a") & F("a").set("b") which currently raises a
(DynamoDB-side) error, but no longer raised one after implementing
eq. Switching from Dict[F, T] to List[Tuple[F, T]] preserves the
current behaviour and invalid update expressions correctly raise an
error.
Fixes #110
