Added two new functions to conveniently call functions/methods from C.

Browse source 
PyObject_CallFunctionObArgs() and PyObject_CallMethodObArgs() have the
advantage that no format strings need to be parsed.  The CallMethod
variant also avoids creating a new string object in order to retrieve
a method from an object as well.
