Hey,

here is the resulting more thorough patch replacing the one before.

It's not finished completely as error handling and reporting via
mm-sec-error is still missing in mm-view-pkcs7-[decrypt/verify].

But displaying verification and encryption information via
gnus-mime-display-security does work (at least in the good case).

See the patch for more information.

I'd welcome any comments :)
