    [app] Use X11-specific API under guards
    
    We should be using X11-specific API (either GDK-X11 or direct
    Xlib calls) only under the GDK_WINDOWING_X11 define.
    
    The only X11-specific code is the slowly_and_stupidly_obtain_timestamp()
    function we ported over from Nautilus. This function only has sense when
    dealing with startup notification on X11, so if we are not building for
    X11 we can safely use g_get_current_time() (we are building a fake startup
    notification id anyway).
    
    This commit should hopefully make Libunique a tad more portable; we still
    need a replacement IPC mechanism for non-Unix platforms, but I hope in
    D-Bus being ported first. Other platforms startup notification mechanisms
    should be implemented in GTK+ already.
