Summary: email.Generator: no header wrapping for multipart/signed

Initial Comment:
The body of a multipart/signed message has to remain unmodified for the signature to stay intact. Rewrapping headers of nested MIME parts breaks signatures.

So I disabled header rewrapping for multipart/signed, by adding a new handler to the email.Generator class.

There still remains an issue about leading spaces in header values breaking signatures. 

The supplied patch is against the latest subversion sources, r54016.
