Now includes increased size variety. Customizable values. The function is;
percentage size variance = +/- e^(x^(intensity) / width) - 1, x being a random number between x min and x max.
Default values are +/- e^(x^8 / 5) - 1.
Also, draugr are fixed.

Spawned draugr will now attack appropriately. Tested that in-game.
