GPGME TOFU support for mutt

[Thomas Glanzmann]

Hello Werner,

> You need to change Mutt to make use of it.

do you know if someone is working on it? If not, can you give some
hints that I could make a patch for mutt ready:

        - What needs to be changed?

        - Which functions need to be called?

        - Is there document that describes what neeeds to be done?

        - Was the change already done to another MUA?

Cheers,
        Thomas
