This was discussed in #706
It also uncovered some off-by-one issues with defining some constants.
A few structs now use rsreset/_RS to define their offset constants, as discussed in #739
`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.
