Random.org results are not properly distributed.

I'm the original author of the EotE roller at game2.com, and as it happens was updating my roller for WFRP (group game change, wee). I just finished last night and then discovered this one - go go wasted effort. :) Anyway, when I was working on my code, I had to adjust the LCM of the dice when submitting and using results from RANDOM.org - for EotE with 6, 8 and 12 sided dice it was 24, for WFRP with 6, 8 and 10 sided dice it's 40. So you'll need to change
face = Math.floor((random * die.sides.length) / 24);
to be / 40 and
randomRequest.open("POST","http://www.random.org/integers/?num="+dice.length+"&min=0&max=23&col=1&base=10&format=plain&rnd=new",true);
to max=39, otherwise conservative and reckless rolls will not be evenly distributed among potential die faces. Probably should have put that in a var :)
