NEXT: Update moves

Triple kick, twineedle, and water shuriken now have perfect accuracy in keeping with the precedent set by other multi-hit moves.
Clear smog is a never miss move and now has 90 base power, allowing for a safer option over sludge bomb.
Quiver dance does not need any NEXT modifications because it will work the same as in OU as discussed in a previous pull request. Gossamer Wing will be changed later.
