[Color Configuration] few improvements

Hi, 
using color configuration tool, we found the way to have good results but I see 3 points to improve:

- 1 the choice of emitters:

Values from manufacturer:

It's very hard to match reality in CIE diagram with pairs like Green Cyan.

- 2 the link between wavelenghts and colors

If we set Lime as 590 nm, eos consider Lime as White in CIE diagram

we have have better results if we let Lime as Lime

- 3 add an option to define values to match °kelvin standard values and set min an max °k

i set home values in fixture editor to match a 3200°K with spectrocolorimeter. When i try 2700K in color picker it works, but after it's impossible to match reality. And also , if fixture goes to 8000 or 10000 k, it's impossible to have it in color picker.
