[pygtk] Win32 file chooser

[John Pye]

FWIW, one small step further: here is a short script that will show the
Windows dialog on windows if possible, and fall back to the PyGTK one
where necessary (on Linux or on Windows without win32all). See attached.

It's only designed for opening files at this stage, but perhaps it can
be taken further.

Cheers
JP
