Use the new notmuch address command to do completion for addresses in
from: and to:. Use --output=sender for both for efficiency, even
though --output=recipients would be more accurate for to: prefix
completion.

This is v2 of id:1422388098-16333-5-git-send-email-jani at nikula.org
opting for --output=sender for both to: and from:. Added a comment to
point this out.
