Correct a few move summaries.

Sonic Boom and Dragon Rage used to have their flat damage stored as the
base damage; now that they have null power instead, their damage will
show up as *, so the summaries should specify the actual damage.

Double Kick et al. used to have a flat damage percentage for both hits,
as if the whole "two hits" part was just flavour.  Now that the actual
power of one hit is stored instead, I can't pretend it's just one
attack.

Also corrected a few instances of "turn" that should've been "action".
