Many uses of random() & value have been turned into random(0, value).
This is not only more efficient, it also ensures better random distribution because the parameter-less variant only returns values between 0 and 255.
For most attack functions this is wrong, it's only the Hexen fighter attack needing this particular value, so it has been split up into two return values now.
