More settings for lamps.
Setting the volume of the illuminated space (distance). Choice of "ray" or "diffuse". Choice of brightness in percentage. Choice of light color. Mode "overflow from one color to another". Mode "overflow of many colors" (no setting, just all the colors of the rainbow passes). Grouping to create general settings (the latter function only through Lua). Outside Lua - brightness setting (mandatory, and make the maximum brightness 4 times higher, otherwise they work too weakly).
