BATTLE_FIGHTER_DAMAGE/BATTLE_FIGHTER_HEAL let a move's own cutscene
apply damage/healing to "target" or "user", resolved from
BATTLE_FIGHTER_POS_TARGET/USER sentinels against the current action by
battleStateExecutingInit. fire/slash now call BATTLE_FIGHTER_DAMAGE on
their target.
BATTLE_POST_MOVE checks fighter health after each move and sets
BATTLE.result (now a real field, previously commented out) to
win/loss, transitioning into BATTLE_STATE_WON/LOST; fleeing sets
BATTLE_RESULT_FLED. All three end states now show a textbox before
moving on to BATTLE_STATE_ENDING.
