Add an option --from= to notmuch-reply.c to restrict guessing of the
From: header. The existing logic looks as the main headers, then at
the delivery headers, and finally defaults to the config file address.
This patch allows the user to restrict which of these guesses are
made. Currently the supported values are:
default|fallback-all current behaviour
fallback-received fallback to delivery headers but not config file
fallback-none only look at from/reply-to/to/cc/ headers
none From: header is always left empty
If the code does not find an allowed address it outputs an empty From:
line and the caller can decide how to respond.
