aokpclock: clock hands based on unicorn horns!! and 2 new dials

PS2 : update preview
PS3 : sharpened hour and minute hand images (sourced from
      original AI files now)
      NOTE: I am being lazy, and not updating the hands
            in the preview. (they are still the old ones)
            I guess that won't make a difference, as
            the blurriness is not visible in preview at least
