3.1.0

• Added support for "container" type items in D&D5e - this is a custom implementation, so other systems' containers will not work out of the box
  • Splitting currencies in item piles takes into account across all currencies across containers in the pile
  • Added tree-like display for items in containers
• Added support for currency exchange in custom item purchase prices
  • If you have configured an item that costs 1 gold piece and 1 magical rock, and you only have 1 platinum piece and 1 magical rock, you now get 9 gold pieces back as change, whereas before you needed exactly 1 gold piece and 1 magical rock.
• Added option for a custom sell price on items, similar to custom purchase price
• Added game.itempiles.API.combineItemPiles which allows you to combine several item piles' inventory into a single item pile
• Added detection for when the GM is unresponsive for item piles to make changes for players
• Fixed localization issue with ITEM-PILES.Trade, now moved to ITEM-PILES.PlayerList.TradeButton
