This is an Open-GL Kss version by R. Paquette

Added, altered or fixed the following while implementing kconfig Settings Group...

bool track : color by velocity or distance from core at birth
bool trail : on/off , leave trails via glBlendFunc (should write a shader)
bool rotate: dumb xyz += 1 world rotation;
bool flyby : start close, get farther as we iterate
bool strings : instead of distributing stars in a disk use a staight line
bool glpixels : use built in GL pixels or a textured panel
int stars : n*1000 = KStars
int galaxies : n
int iterations : n tics until next big bang
int delay : ms srcreen refresh
int maxMass : max galaxy core mass range
int starSize : GL point size
float galaxySize : radius 0.1 to 1.0
