[evolution] Show parts with Content-ID of multipart/mixed as attachments

[Milan Crha <mcrha src gnome org>]

commit 186f5dbd1fc9f5fe3292b5f07277f6d403c5ca99
Author: Milan Crha <mcrha redhat com>

    Show parts with Content-ID of multipart/mixed as attachments
    
    The multipart/mixed should behave differently than multipart/related,
    because subparts of multipart/mixed are not meant to reference each
    other by default, thus the subparts should be shown as attachments.
    This was reported at https://bugzilla.redhat.com/show_bug.cgi?id=947409
