Title: thread: Detect inline and separate attachments

If an email contains both inline and separate attachments, the previous logic would detect all the attachments as inline.

Separate attachments have the `cid` set to `false`. This will pass the `isset` test, which would cause the logic to search through the body for a string of `cid:`, which would very likely be found if there was another inline image somewhere in the body of the email.
