Introduce new Dungeon mode

Goal: To minimize minting of UMY daily which will solve UMY price falling

Plan: Introduce new dungeon mode, wherein we will have 2 dungeons, 1 is the current dungeon, the other is the one with less UMY that can be farmed. These 2 dungeon modes will have a cool down, and cannot co-exists on the same day, (e.g Monday-Thursday open dungeon 1 only, Friday-Sunday dungeon 2). Dungeon 1 will have the current UMY farm setup but harder monsters (this way players will be forced to evolve their pets), while Dungeon 2 will have less UMY but weaker monsters (guarantee that we can farm UMY at least). It might also solved bot-ting (hopefully, because if the user with bots didn't evolve his pets, he will have a hard time farming on dungeon 1)

To summarize: Dungeon 1 = current UMY farm setup but harder monsters, open only from Monday-Thursday Dungeon 2 = less UMY per day (open for discussions) but weaker monsters, open only from Friday-Sunday
