DKIM body hash with multipart/related

[breedbekkikker]

When using Gmail's web interface to send an email with an inline image (copied from clipboard), the mime message is multipart/related. The first body part contains a multipart/alternative section. The boundary following the last body part of the multipart/alternative section and the boundary of the next body part of the multipart/related section are separated by a single CRLF. E.g.:

--e89a8f647253643e8f052238e631--
--e89a8f647253643e93052238e632

However, when using the DKIM Verify function to verify the Gmail message, the body hash is calculated over a body with an additional CRLF between these two boundaries. This results in falsifying these kind of Gmail messages.

I've released MimeKit 1.2.14 to NuGet with the fix for this bug.

Great! Thanks a lot!
