* src/modest-tny-mime-part.[ch]:
        * New method to know if a TnyMsg instance is really a message
          or in fact it's a direct attachment.
* src/widgets/modest-attachments-view.c:
        * On setting a message, if it's an application
          multipart/related, show its contents as attachments (should
          help showing smil messages).
        * On setting a message, if the top mime part is a file, then
          show it as attachment.
* src/modest-tny-msg.c:
        * Modify code to detect body, to take into account the
          application multiparts (as smil) and direct attachments. These
          shouldn't show a body.
        * On creating forward messages, attach properly the direct
          attachments (we don't show any body for them).
* src/maemo/modest-msg-view-window.c:
        * Manage properly the application multiparts and top mime part
          attachments.
* src/modest-formatter.c:
        * Modify attach method to work if body is NULL.
