kasrkin elite rule update

[jmegner]

Kasrkin elite ability can now modify a 2nd die from a fail to normal success if another die is discarded:

Each time a friendly KASRKIN operative fights in combat or makes a shooting attack, in the Roll Attack Dice step of that combat or shooting attack, you can spend 1 or more of your Elite points to adjust one (and only one) of your dice. After adjusting your first dice, if you discard one of your attack dice, you can spend Elite points to adjust an additional dice, but only one of your remaining failed hits to a normal hit. For each point you spend, add 1 to the dice result and reduce the number of Elite points in your pool by 1. In each Strategy phase, add 2 elite points to your pool.
