Mighty morphing rings

• The concept of Rings that affect your appearance has been added. If a custom wearable ring has an appearance ID associated with it, and AppearanceId.java also knows that appearance ID is associated with a ring, then it is a morphing ring.
• Fixes issue where player appearance was sent every tick in order to get Cabbage Easter event out in time
• Fixes issue with ::becomeNpc when specifying a slot to wield the npc in
• Fixes another issue that could cause combat style desync: server will no longer remember your combat style across logins when logging in to authentic clients
• Fixes the ::wipeinventory command to be able to work on other players.
