Realistic stars

Blue stars are hotter than red ones, but for some reason have a higher chance of harboring cold planets. A small tweak to stars to fix this small discrepancy would be nice :D

Also starless systems should be dead and frozen, not "no preference for different planets"

Edit : Thanks for the idea, Orbotosh! It would indeed be interesting to have more weird endless-affected planets that don't follow the laws of physics as we know them.

Edit2 : Great suggestion, nats! Having the sophons blow up their star as well would be quite entertaining! Some sort of solar-manipulation late-game tech that would change the system's stats or something would be very cool.
