Support encrypted mails forwarding

Summary:
Some notes:

- What we do is: if the mail is encrypted, decrypt it and copy its content into a new message (with plaintext, html and attachments, if any), and use this message as attachment for forwarding
- The `isEncrypted` function from KMime doesn't seem to detect every kind of encrypted mails. AFAIK this structure is not detected:
  - `multipart/mixed`
    - `text/plain`
    - `application/pgp-encrypted` (attachement, named "ATT00001")
    - `application/octet-stream` (attachment named "encrypted.asc")
