    shell: use g_value_transform in setSongProperty dbus method
    
    This mostly means that the caller can use any numeric type for setting
    properties such as play count.  Since dbus-glib doesn't map any dbus
    value type to G_TYPE_ULONG, it wasn't possible to set the play count,
    track number, disc number, or year previously.
