EI: Redesigned the lich identity revealing system, and other tweaks

Instead of letting the RNG determine how quickly you find Mal-Ravanal, you now have to either kill X of the liches or reveal all of them by attacking them. If revealed by killing X liches, he will appear as the remaining lich farthest away from Dacyn. As a counterbalance, the liches are no longer given extra gold for each loss. Most likely requires some more balancing, as well as dialogue improvement.
