This patch extends the template specialization of PythonFormat structs
and makes use of the pre-existing PythonObject class to format arguments
and pass them to the right method, before calling it.
This is a preparatory patch to merge PythonFormat with SWIGPythonBridge's
GetPythonValueFormatString methods.
