[crossfire] current plugins with python 2.2?

[Mark Wedel]

  metalforge ran into some problem with latest cvs version of crossfire in the 
python plug.  metalforge currently has python 2.2 installed.

  My fix was to add a return near the top of addConstants().  The crash was 
happening someplace inside of this call:

      new = Py_InitModule(tmp, NULL);

  It may be that calling convention for this is different in python 2.2

  All that said, couple solutions:

1) require newer version of python (as with python 2.2, it clear seems broken)
2) Look at python 2.2 doc and figure out if code can be modified to work with it.
