Add Guilds, and Guild Halls

Hi, I would love to be able to form Guilds in this game. After you join a Guild your player's name will get a prefix of the tag from your Guild as a way to represent your Guild in the game. Also, once in a Guild you could load into a common area the "Guide Hall" where you could interact with other Guild mates. Also, the Guild Hall could include training dummies so you could practice your spells and abilities. Also, there could be Guild banks where you could store unneeded loot in the bank. It could require a deposit and withdrawal fee, maybe 25 gold (higher than trading normally), so that it just doesn't become a way to trade items freely and not break the economy. The Guild Hall could also be upgradable to let more members into your hall at one time. Also, you could upgrade your Guild Hall to have dueling chambers where you can duel your friends in a no consequences duel. Finally, you could upgrade the Guild Hall to spawn in pve mobs where you could practice fighting pve mobs.
