Script New Visual Battle - Por João Neto - www.jogosrpg.com.br

Este Script faz uma pequena modificação na batalha, exibindo
as faces dos heróis. Com ele, Todas as chamadas ao método
draw_actor_face agora possuem opacidade, podendo adicionar
este parametro em outros lugares do Script em geral.

Para usar, apenas Cole Acima do Main.
