Use custom tray icon instead of GTK stock

Use the "Anonymous Cards" image from openclipart.org
(http://openclipart.org/media/files/Anonymous/12230)

This same image is used in other new FPDB icons, but the combinations
with looking-glass don't look good in systray. This icon is plain enough
to work properly even when scaled really small.
