Win32 binaries for GTK+ 2.4.9

[Tor Lillqvist <tml iki fi>]

Fresh GTK+ binaries (DLLs etc) and an updated GLib 2.4.5 DLL are
available at www.gimp.org/win32/downloads-20040902.html .

This is GTK+ 2.4.9 plus the patches for bugs #145467, #151090 and
#151581.

I also recompiled the GLib 2.4.5 runtime to include the fixes for bugs
#147392, #141124 and #150394.

Unless somebody reports some serious problem with these binaries, I
will make that page into "downloads.html" in a few days.
