Gen III contest effects were part of the initial data import from brown
veekun and so have probably never gotten a proper rip.
This commit re-rips contest effect stats, types, combos, and the mapping
between contest effects and moves.
None of the stats changed (jam & appeal); a few moves got assigned
different contest effects (specifically: smokescreen, flash, spite, and
shadow ball); and several combos changed.
For example, Hail was listed as comboing into the following moves
(this is also what Bulbapedia says):
Ice Beam, Blizzard, Aurora Beam, Haze, Powder Snow, Icy Wind,
Ice Ball, Weather Ball, Sheer Cold, Icicle Spear
However, the actual list is much shorter:
Blizzard, Powder Snow, Weather Ball
I verified on my Ruby cart that Hail->Ice Beam and Hail->Icy Wind are
not real combos, and that Hail->Blizzard is.
n.b. There are a bunch of unused contest effects in the game: out of 48
effects, 15 are not used by any move. The pokedex doesn't currently
include these. I elected not to add them, partly because i didn't want
to have to rip flavor text for them, but mostly because if i were going
to go that route i would probably reassign contest_effects.id to match
their internal ids, which would have made for uglier diffs.
