Now they can say something:
-When their last Pokémon's HP is between 25% and 50%.
-When a critical hit is dealt to their first Pokémon for the first time.
-When a super effective hit is dealt to their first Pokémon for the first time.
-When a STAB move is used against (but doesn't faint) the opponent's Pokémon.
-When the Player's Pokémon's move doesn't affect the opponent's Pokémon.
-When they're about to trigger a Mega Evolution.
-When they're about to trigger a Z-Move.
Misc. changes:
-Split GetEnemyMonCount for readability's sake.
-Optimized the size allocated to trainerSlideLowHpMsgDone.
Mimicry is now a proud member of ABILITYEFFECT_ON_TERRAIN.
Misc. changes:
-Ditched the dependency on and usage of gBattlerAttacker for the effects inside ABILITYEFFECT_ON_WEATHER and ABILITYEFFECT_ON_TERRAIN.
-Made Cmd_switchineffects activate ABILITYEFFECT_ON_TERRAIN to take into account overworld weather-induced field terrains.
-Updated the text strings printed by the battle scripts inside the aforementioned AbilityBattleEffects caseIDs.
-Removed constant label of unused VARIOUS_TRY_TO_APPLY_MIMICRY which I forgot about.
-Updated ChangeTypeBasedOnTerrain, partly as a result of the aforementioned changes but also for optimization purposes.
-There was never a reason to establish an empty scope, or to use GET_MOVE_TYPE and the variables that complemented it.
-Removed case ABILITY_QUARK_DRIVE from AbilityBattleEffects' case ABILITYEFFECT_ON_SWITCHIN.
A new, probably better way to handle the announcement trigger that abilities such as Protosynthesis and Quark Drive have, when the battle weather or the field terrain change.
Misc. changes:
-EFFECT_DAMAGE_SET_TERRAIN -> EFFECT_HIT_SET_REMOVE_TERRAIN
-It's more appropriate as the effect can be used to force set a terrain or simply to remove an active terrain, after all.
-The main reason for the rename was the inconsistency with the battle script's label.
-Reverted accidentally committed change to B_DOUBLE_WILD_CHANCE, performed back in c8abf00c.
-Renamed TryActivateWindRiderLoop to BattleScript_TryTailwindAbilitiesLoop
-Modified how it handles the check for Wind Rider by using a various and incorporated Wind Power into the mix because that ability is affected by Tailwind as well.
-Added a modifybattlerstatstage macro to handle stat stages in battle.
-Rewrote the checks inside the case ABILITYEFFECT_MOVES_BLOCK of AbilityBattleEffects.
