Add Milly

There is currently a bare-bones version of Milly, without any quest, until we can decide on what her quest will be.

• She wants to be impressed by the exploits of the player, gives a Beanie Copter after completing some quests and having X boss points.

• Decide what to do of Boss Points, Candor and Milly's quest.
• Replace Beanie Copter with a more suitable item reward.
