Villager Overhaul

3.4.2: Stopped logic that allowed for a cheese-strat. When rerolling for items, we keep track of the amount of rerolls (per trade offer) i.e. "V" per item, per player (global). Therefore, canceling an Auto-Reroll sequence and starting over will no longer matter. Also show "V" in item tooltip on AutoSearch/BusyScreen/PaymentScreen.

3.4.3: If player doesnt have enough emeralds, AutoSearchPaymentScreen will show "Not enough emeralds" instead of "Waiting on server..."

3.4.4: Fixed trade-offer discount calc drift bug due to locked offers reapplying discounts. For affected villagers, use command /vo_fixgenprices [radius] (this will also reset Cured Villager discounts, beware)
