Added dungeon environment selection to enable lower game difficulty. — The Rings of Powder Steam update #997757

Our Elvish data center has reported to us that the game's difficulty level is too high for some players. To this end, the necessary updates to the palantirs have been made. Now, by choosing a "Relaxing" ( most easy ) or "Calm" dungeon environment, our mages will ensure that the dark pit monsters appear less often and do not cause as much chaos in the underground kingdoms of our players.
