* Casting a skill now plays the corresponding overlay(if any). * Prevent a crash caused by nil pointer in HeroSkill deserialization, happening when unmarshalling HeroSkill from packets as a remote client. * Add PlayerAnimationModeNone to handle some of the Skills(e.g. Paladin auras) having "" as animation mode. * Joining a game as remote client now waits for map generation to finish before rendering map or processing map entities. This is temporary hack to prevent the game from crashing due to concurrent map read & write exception. * Send CastSkill packet to other clients.
