Keep perceived contrast in random background color
Randomize colors using HSLuv color space instead of HSL. It has
perceptually uniform lightness, which means every color with the same
lightness value is perceived as equally bright by humans. Displays
quality and lack of calibration in most monitors lowers this uniformity,
but even on worst color display it should be better than standard HSL.

- Random seed takes PID into account to prevent repeated colors in separate Konsole processes
- Key names in a config were changed
- Adapted "Black on random light" color scheme
Breeze with random ranges on default bg and fg: hue=360° saturation=100:
To be done in future:
- Automatically convert color schemes which use old randomization method.
