[pygtk] Reload gtk.Image contents

[Niklas Koep]

If you're updating your gtk.Image contents via its set_from_file() method
you don't need to request an update at all -- it happens automatically.
Generally speaking, however, gtk.Widget implements a queue_draw() method
which can be used to invalidate the entire visible area of a widget which
in turn causes it to be redrawn. For your use this doesn't seem to be
required though. Hope this helps.
