Fix for METH_O and -compactdefaultargs, in two parts:

  - Don't mark a method as METH_O if it has compactdefaultargs
  - In SWIG_Python_UnpackTuple, allow for a non-tuple 'args'.

Added compatibility for python versions 2.3 and 2.4.  These are only
partially supported; inheriting from wrapped types looks problematic.
Versions older that 2.3 are unlikely ever to work.
