Feature Request: Define "Random Dungeon" Scenario so loot deck can be prepared appropriately

[designbot]

When generating a random dungeon using the variant described on pages 70 and 71 of the rules, the loot deck should include 24 cards: 12 money cards, two cards of each material resource, and one card of each herb resource. It might be helpful to have "Random Dungeon" available as one of the scenarios, just to prepare the loot deck appropriately.
