TWO ability points per level now ~ whaaaaaat ~~

You heard that right. Heroes now get not 1 but 2 ability points per level.
Suture potency increased: 20 + L*(Le/6 + De/4) --> 20 + L*(Le + De)
Poison Weapon AP cost decreased: 50 - L --> 30 - L
When traveling in Caverns, any friendly dwarves in play will now start out in front.
Fixed several Caverns battle log bugs, like null/undefined unit names, and keeping your position while scrolling.
Limited the number of initial caverns mobs to 1~5, to avoid overwhelming heroes before they've had a chance to buff/summon.
