v1.56-ALPHA for MC 1.6.2, 1.7.x, 1.8.x

This version is marked as ALPHA, because it is including a bunch of internal changes which weren't properly tested yet and which might especially affect trading and saving of shopkeeper data. This version is currently only meant for testing purposes and finding potential issues.

Please create a backup of your shopkeeper save.yml file before using this version.
You might especially want to check if all shopkeeper trades get properly loaded and saved, and if the setup of shopkeepers, trading and item removal and disposal in/from player-shop-chests is working properly.
If you discover any issues please let me know by creating tickets for those.

• Removed custom item comparison, which was used in the past to only allow trades if the required and the offered items perfectly match, excluding internal attribute uuids. This is now useless, because of changes in minecraft's 1.8.x trading logic.
  Unfortunately detailed debug messages, telling exactly why certain items are not similar, are no longer possible with this change.
• Updated to minecraft's new 1.8.x trading logic:
  Previously minecraft did unlock a trade if the type of the offered items matches the required item. Now in MC 1.8.x if a trade requires an item with custom data, such as custom name, lore or attributes, minecraft only unlocks the trade if the offered item perfectly matches the required one (all the item's internal data and attributes have to be the same).
  If the required item has no special data, then any item of the same type, even items with special data, can be used for this trade.
  Also, minecraft sometimes unlocks a non-selected trade, if the required items of a different trade is matching the ones which are currently inserted.

Shopkeepers is now trying to allow most of those trades as well. So if a trade requires an item without special data, every item of that type is accepted. If an item with special data is required, only perfectly matching items are accepted.

• Added setting use-strict-item-comparison setting, which defaults to true. When this setting is active trading behavior is nearly the same as before: An additional and more strict item comparison is performed before a trade is allowed, which makes sure that the items offered perfectly match those of the used recipe. So even if the required item has no special data, only items of the same type which as well don't have special data are accepted. Otherwise the trade gets blocked.
  This setting's default is currently set to true, to prevent potential issues with already setup shops, which expect the old/current trading behavior. Also servers running on MC versions below 1.8.x might depend on this setting to be active.
  For servers using the latest server versions I recommend disabling this setting, so that the trading logic better matches the one of minecraft.

• Changed: Resetting the player's selected chest after successfully creating a player shopkeeper. This seems to be more intuitive.
• Fixed: the default shop-created message for the buying shopkeeper did say that one of each item which is being 'sold' has to be entered into the chest. Instead it was meant to say 'one of each items being bought'.

• If the trade for a written book fails players can sometimes still open and read the book if they close the shop and click the temporary fake book in their inventory fast enough. There is not much I can do about this..
• Server crashes and improper shutdowns might cause living non-citizens shopkeeper entities to duplicate sometimes.
• The 'always-show-nameplates' setting is no longer working on MC 1.8.
• Compatibility with older bukkit versions is untested. If you encounter any problems let me know and I will look into it.
• A bunch of entity types are only meant for experimental usage. They might cause all kinds of issues if used. See changelog of v1.50.
• In the latest MC 1.8.x versions default minecraft trading logic has slightly changed (and by that those of shopkeepers as well): if a trade requires an item with special data (like a custom name, etc.) minecraft is now only allowing this trade, if the offered item is perfectly matching, including all special item data and attributes.
