Fix platorm inconsistency in Python default argument handling.

Browse source 
32 bit and 64 bit compiled versions of SWIG generated different Python files
when default arguments were outside the range of 32 bit signed integers.
The default arguments specified in Python are now only those that are in the
range of a 32 bit signed integer, otherwise the default is obtained from C/C++ code.

Closes #1108
