[PATCH] lei import: non-noisy by default, add --noisy switch

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

Email::Address::XS is too noisy by default to be useful given
the poorly formatted messages which exist in history.  Quiet it
down by default since users often don't have the means to fix
such historical messages anyways.
