create alias round_teeth -> upper_teeth
Seems to be used for the same thing.
While this alias would make more sense the other way around at first glance (round teeth has a wiki and is tagged on much more posts) I think way is better since not all upper teeth is round while all round teeth is "upper". I can accept an implication from round teeth to upper teeth instead if that's desired but I really think we should do an alias.
