Add the voice_tag parameter to Character, and config.voice_tag_callback.

To support the new voice tag feature, character gains a voice_tag
parameter, and the new config.voice_tag_callback variable comes into
existence. When a character speaks, config.voice_tag_callback is
called with that character's voice tag.
