display the real accuracy in actor's tooltip for each weapon they are holding.

The current accuracy displayed in tooltip is usually incorrect. It uses unarmed accuracy, which is affected by enemies' innate accuracy. For example, netherworms and many other races have 500 accuracy for unarmed attack, and when they become random rare/unique/boss with a normal weapon, their actual accuracy is significantly lower than unarmed accuracy that is displayed in tooltip, which is very misleading.
