pyobject.int64: New method to convert integer object to Octave int64
* __py_struct_from_dict__.cc (F__py_int64_scalar_value__): New function to
extract int64 scalar value from a pyobject.
* @pyobject/pyobject.m: Add conversion method int64 as a wrapper around
__py_int64_scalar_value__. Add %!tests of int64 value extraction.
