* Prevent turning on tellduslive lights with 0 brightness
It was possible for the light compontent to get in a state where the last_brightness was set to zero, and when turning on (by calling turn_on) it would call the TellStick with 0 dim level, ergo not turning on the light.
With this, it will fall back on a 75% dim level if the level is set to zero.
* Wrap long log line over two lines
And using a more proper way of formatting the message
* Fallback to 100% instead of 75%
