[MKM] Implement Kaya, Spirits' Justice and new zone change batch event

So what is the difference between ZONE_CHANGE_GROUP and ZONE_CHANGE_BATCH?

Code looks fine now, just want to make sure documentation is clear for future devs.

ZONE_CHANGE_BATCH contains all zone changes that occurred in a single action, whereas ZONE_CHANGE_GROUP only contains changes that occurred between the same two zones.

For example, paying a Craft cost by exiling a creature permanent and a card from your graveyard would fire 1 ZONE_CHANGE_BATCH event but 2 ZONE_CHANGE_GROUP events. In this instance, Kaya's ability should only trigger once.

compare UUID with equals rather than player objects

ZONE_CHANGE_GROUP and related usages will be replaced by ZONE_CHANGE_BATCH in the future (group event has buggy/wrong logic and duplicate events in some use cases). Batch logic is correct.
