Adds support for Python __r*__ operators (by Karl Wette)

Browse source 
The Python operator model, when evaluating e.g. x + y, is to call
x.__add__(y), then y.__radd__(x) if the former does not exist, etc.
This patch adds similar functionality to the SWIG runtime code.
For the special case of the comparison operators __l*__ and __g*__,
the reverse operators are __g*__ and __l*__ respectively.
