Add support for Lohas 9W bulbs

[steveway]

It seems to be very similar to the ITead Sonoff B1, so it's based on that.
This should be the official product page if I'm not mistaken:

Tried out today... Found ITead is similar but not same.

You have then 5 Channels: R,G,B and 2 White LED's and at this Point i don't understand if that is well or not.

I tried this out on E26 9W, RGB Works, White temperature does not change. Are there further possible outputs that can be mapped beyond 0-4.

Mhh, I moved recently and can't test my light at the moment.
I need to reflash it for that, currently I don't have the ability because I'm missing a place to solder here.
I think if I remember correctly the temperature is controlled by two different sets of white LEDs, I'm not sure if Espurna does support controlling that this way yet.

Are you sure that there is a real white channel??? This Lamp ist RGB only...

I cracked open the bulb to find out what was really happening. Channels 0-2 control the RGB LEDs, channel 3 controls (4 white LEDs) and channel 4 controls (4 white LEDs). All 8 of the white LEDs are the same temperature. With the factory installed firmware, I set the bulb to a warm temperature and it uses the white LEDs + the red LEDs. When I set the bulb to a cool temperature it only uses the white LEDs.
