extra parens elimination of unused vars.

- Added check to avoid pickling module __main__ for classes that are
  defined in other modules, in whichmodule

- Changed to use Py_eval_input rather than eval_input.

- Changed to use SIZEOF_LONG macro to avoid warnings on 32-bit machines.

- Added option of supplying None to pickler, which cases no data to be
  written during pickling.  This is slightly useful, in conjunction
  with persistent_id attribute to find persistent sub-objects without
  writing a pickle.

authentication required.

  * european-style dates like 27/5/1997 were raising
    parsing errors - this was originally intentional

    the existing c DateTime module does accept this
    format, so now this version does too for compatibility.
    NOTE THAT YOU ARE ALMOST CERTAIN TO HAVE PROBLEMS
    WITH THIS FORMAT AND SHOULD USE IT FOR COMPATIBILITY
    ONLY! Date strings with a day less than 13 will
    give incorrect results due to the abiguity.

logic will be needed for any C-based persistent object.

Added minimal index variety.
