Added the writeNoneReturn method to CppGenerator to attribute Py_None

to the Python method wrapper return variable, after a call to a C++
function that returns void, but only when any of its other overloads
has a return type different from void.
Also documented the CppGenerator::writeOverloadedMethodDecisor method.
