[RAS] handle obfuscation

  Following off that meeting, I have come with a simple way to
  obfuscate dates in handles. Just use the length of a handle as a
  delta. Thus if the handle is RePEc:per:1965-06-05:thomas_krichel
  move it to RePEc:per:1965-07-10:thomas_krichel since the length of
  the handle is 35 characters. If this something you would do, I can
  write a piece of python than would implement conversions. I'm not
  sure whether this would work if we have fictious dates in the data,
  like 1965-06-31.  I could run a test on the current RAS data.
