[PATCH 02/17] lei: favor "keywords" over "flags", test --no-kw

[Eric Wong <e@80x24.org>]

JMAP brain says "keywords", IMAP brain says "flags";
JMAP brain wins today.

Since "keywords" is a bit long, support "kw" as a shortcut since
there's no conflict and "kw:" will be our search prefix for
looking up messages by keyword.
