User-friendly keysigning that verifies that key belongs to the recipient

That is, caff-style keysigning. Ability to output an email that can then be pasted into some kind of (local or web-based) MUA.

caff (from the signing-party package) adds around 1MB to the ISO size, and is well-established. Its main drawback is that is requires a configuration file and duplicating at least some gpg.conf settings into ~/.caff/. It has been part of Debian for a long time.

monkeysign supports basically the same usecases, but without these drawbacks.

See sub-tickets for the next steps.
