Added juggle counter (special training settings)

I crudely adapted the juggle counter (airTimerView) from crystal_cube's trial mode. I didn't write most of this, just "ported" it.

I added Chun EX Legs as a reversal option, since multiple people have asked me about it. Messing with the counter attack delay is an annoying part about this move if you use a recording, so I integrated it right behind the KKZ option
