Wall control board for smart home

Control/monitor four switches with buttons/leds.

based on MQTT/UDP protocol.

To configure topic names for switches, see mqtt_map.c:

struct mqtt_io  mqm[] =
{
    { "Light5A",        0 },
    { "Light5B",        1 },
    { "Light1A",        2 },
    { "Light1B",        3 },
};

String is a topic name, number is channel (button number).
