QoL change for Mad Berserker

[sharkinajar]

Change the Level 8: whirlwind (since it doesn't pair well with dual-wielding and is buggy anyways) to improved twf or something else (war cry 1/day?)

As whirlwind attack can bug your PC, I have made some changes. Available next reset for the very, very few foolhardy Mad Berserkers.
