This release updates the dependencies used by the library and fixes badly formed test data.

We use Enmime to parse the raw email (.eml) files and enmime is no longer as lenient about badly formed header lines such as illegal characters, or missing : from header names. This is the way it should be (at least these days), so the test data was corrected.

As of this release, if you wish to parse and analyze old email archives, you will need to perform a little pre-processing.
