This adds separate permissions for accessing, creating and destroying of shops.
It also adds a config entry to allow using of a shop even if someone have access to it due to their permissions.
The InventoryMoveItemEvent is now only used for Hopper Minecarts, other blocks that could move items (Hoppers and Droppers) are checked on place. That way players that have access to a shop can just use the blocks normally but other players can't place them.
This uses hardcoded widths for the main characters used in Minecraft and might not be precise for some characters but better than the previous 15 char hard limit.
This also makes it possible to input IDs on the sign that are longer than the max sign letters that the plugin uses as that just gets auto corrected back down to the correct amount.
This includes a new price_precision config entry to set the amount of decimal places to allow on a shop sign (set to 2 by default). Thanks to @andrewkm for this idea.
It also fixes an issue where a zero inside the decimal places was removed instead of it's end and also removes the point and zeros from prices that only have trailing zeros to avoid confusion (e.g. in languages that use the decimal point for thousands)
This uses a cache for players that we haven't found before so to not check the cache too often and also checks if the online mode of the queried OfflinePlayer matches the server's mode (gotten from the first logged-in player in order to be compatible with BungeeCord requiring the server to be in offline-mode.
This introduces a new AccountCheckEvent to check if a user actually has an account with the used economy plugin. Also fix CurrencyTransferEvent logic (even though it's not used anywhere currently)
Iirc this was only async for database logging or name resolving. Neither of these is done anymore and async access of the Bukkit API can lead to strange problems like the CME described in the mentioned issue.
