python_loader plugin passes input and output objects as gobjects to python

Submitted by Ignas Mikalajunas

Description

There is no way to do anything with generic gobject objects in python, so you can't do any reading/writing in a python plugin. It used to be passing filenames, but now someone fixed it.

Fixing it to pass filenames would work, though i guess adding a pythonic wrapper for GfsOutput and GfsInput would be the right way.
