The PyExtensionClass_Export() function requires a pointer to the module
dictionary so that it can add itself to the module.  Unfortunately this
requires that Py_InitModule to have been called before hand.

I guess this means that the current ExtensionClass API will need to be
modified in order to allow ExtensionClasses to be initialised before
Py_InitModule.
