to prepare potential extension for e.g. 5 colors as used in color scripts

- Handle script errors which occur only in .call(), not just parse errors from .evaluate().
- Hand over an array, not just a variable arguments list.

The algorithm prefers the inner colors (1-2-3-4-5) over the outer colors as the
noise function output is a Gauss distribution. To make the colors set from thr
outside more persent, shift them from 1 and 2 to 2 and 3.

Also, format the algorithms.

- Set default ramp value to center (20) as in plasma.js
- Add and improve code comments and their formatting
- Make value calculation explicit to make them available for debugging
- Keep plasma and plasmacolors in sync for comparability.

and add documentation in template empty.js

Also fix several off-by-one errors, such as the edges being out of sync and evaluation of integer properties.
Also let the marquee color take effect and not just add to the existing RGB values.

Apply only the limited amount of colors when switching e.g. from
ballscolors to balls and back.
Previously, balls would toggle between color 1 and color 2 while it
accepts only one color and the second color is not configurable (v4 / UI)

where the signal infrastructure had been changed to enable the VC widget for color selection.

Integrate with latest changes in devtool (color picker).

and catch up the different colors from the color inputs.
