MCBSP version 2 loading in the engine.. Some very ugly code (will be rewritten). Also, I haven't thought of how bboxes will round to hull sizes yet, so don't even bother trying to use the format yet. Also, someone might want to add a dhullinfo_t instance in the model struct or something, so the rounding functions would be able to access the hull sizes. I'm not sure how that will all work yet.
