5 daysfeat(accent): light IKEA TRADFRI colour bulbs in the accentDanilo M.1-0/+152
udt-bulb fades every paired colour bulb to the wallpaper accent through the TRADFRI gateway's local CoAP API, over DTLS-PSK via libcoap's coap-client. --pair trades the gateway's security code for an identity of its own and records the colour bulbs in ~/.config/udt/tradfri.json. Takes udt-ledstrip's on and off. A bare run, as udt-accent starts it, skips bulbs that are off, since the gateway switches a bulb on for any colour change. Colour and brightness go in separate requests, colour first: combined, or with a colour sent during a brightness fade, the gateway drops part of it.
