On: Twi.bz: the transparent URL shortener

If the original is shorter, just return the original. You can make a note as to why you gave back the original, but I think we can safely assume the user wants the shortest he can get, so give it to him.

But if they add URL click tracking, you still might want the new URL, even if it is longer.
