[PR] Mutant races are selected through character creation

[kyle2143]

We should not remove the spacebux cost from mutantraces. Our mutantraces are rather bland. Basically human reskins. Mostly for funny gimmicks like skellingtons and cows. But they have no official lore behind them and their whacky appearance is the only large difference between humans apart from being considered non-human by the ai. Lizards have even less differences than cows and skellingtons who bleed milk or heal from milk, they just get infra red vision.

Mutantraces should feel more unique before making them feel commonplace. Humans are always the default all-rounder, and I like that. Mutantraces should fit into lore and should have actual substantial pros/cons if they are meant to be commonplace.
