For some reason I thought BattleAnim_Ret was never used, due to how the
battle anim loop would be exited early from. It seems I was wrong.
Removing commands before anim_ret without it being part of the `enum`
seems to break things.
I mean, technically, being able to read beyond a data table's size is
bad practice, but there's so many cases of this that it's not worth
mentioning.
For most of these cases, at least, it's safe to assume the index won't
ever get high enough to surpass such a table's length, because it's
either hardcoded or decided by the game without the use of
uncontrollable data. As such, they don't expose any actual bugs.
Some of the TX_ commands didn't use the TX_ prefix for their
constants, and the label names were inconsistent. I've chosen to adopt
the `TextCommand_` prefix as opposed to `Text_`, as it has a clear
difference in namespace compared to the possibly-used `Text_` namespace
for actual dialogue text.
