Facial expressions should appear with dialog

[Poobslag]

There's a few approaches to this, it could be a little square window next to the text with a facial expression, or some games have a static facial expression there but big pretty character graphics above the text.

For now, let's just have support for one face with about 12-14 expressions. This should be comingled with the dialog, perhaps with some kind of a keyword like {face:00}, {face:12}.
