Fix some constants surrounding sprite animations

Also commented the use of the field surrounding the struct
initialization functions.

SPRITEANIMSTRUCT_0C -> SPRITEANIMSTRUCT_VAR1
SPRITEANIMSTRUCT_0D -> SPRITEANIMSTRUCT_VAR2
SPRITEANIMSTRUCT_0E -> SPRITEANIMSTRUCT_VAR3
SPRITEANIMSTRUCT_0F -> SPRITEANIMSTRUCT_VAR4

BATTLEANIMSTRUCT_01 -> BATTLEANIMSTRUCT_OAMFLAGS
BATTLEANIMSTRUCT_ANON_JT_INDEX -> BATTLEANIMSTRUCT_JUMPTABLE_INDEX
BATTLEANIMSTRUCT_0F -> BATTLEANIMSTRUCT_VAR1
BATTLEANIMSTRUCT_10 -> BATTLEANIMSTRUCT_VAR2
