Out of the current two most prevalent official conventions, this one was
chosen, because they're used in a direct counterpart to this game, and
thus feel more accurate.
`hittarget` was misleading, as it doesn't actually "hit" the target, it
only plays the animation. As such, I've renamed it to `moveanim`.
`checkfaint` has nothing to do with checking if the user or target has
fainted, instead, it applies wCurDamage onto the target's HP, hitting
the substitute if applicable. I've renamed the command to `applydamage`
and all of its subfunctions accordingly.
Two bugs related to not raising the substitute when it should, one bug
related to not running king's rock when it should, and the other related
to running king's rock when it shouldn't. Fun.
The comments seemed to specify that `endloop` loops back to the command
before `critical` and executes that, which simply isn't true. It loops
back to `critical` itself, and executes `critical`, before continuing on
with the remaining commands.
