The opcode wasn't updated for 7.20h, and I think was overlapping with
some status effect list one (hence the weird stuff happening in the
update showcase video.) Also updated the testdata, even though it wasn't
needed.
I also added back the actor hp/mp update, because I deleted that
thinking it would fix something but it didn't.
This now works and Kawari has achieved basic multiplayer! This is of course with
a hundred caveats:
* Previously spawned players are not backfilled
* There is no range or zone detection
* They are carbuncle clones of you, not the other character's data
But it actually WORKS!
