-- featherweight spell now counts only duration out of chests.
-- featherweight duration cut to one-third.
That means, if you play for more than 8 hours a day, this is a downtune, and
if you play less than 8 hours a day, it is an uptune. Idling and LD count as
active playing, so please learn to chest your items if you're not going to be
online and active.
Effects take place at reboot. Old fw's should be back-compatible. If there is
any nonstandard effect that gives a yellow glow, please let me know, because
if it is not updated properly, it will not function at all.
