    Set default for key_menu_screenshot to 0.

    In #364 I recommended -1 as the default to avoid taking screenshots in
    some situations where a key event is posted for key 0. It turns out
    that wasn't such a great idea, as -1 is not parsed properly by the
    config parser, and is shown as ??-1 in the setup tool. Default to zero
    instead, and add guards to prevent screenshots being taken by mistake.

    Thanks to Alexandre-Xavier for pointing this out.
