Adding a (hopefully) failing test case for #52.
* Since Django requires that the content stored in a TextField be unicode, we
need some way to encode the message safely. In situations before where
a single-byte non-7-bit-clean encoding were used, django-mailbox could
explode when writing the message copy to the database; this should ameliorate
that problem.
* Reverts earlier changesets' encoding normalization.
