Auction House Plugin

in the last version (that isn't available anymore) there was a small issue, because the plugin had a different folder called SimpleAuctions (I thought about renaming the plugin, forgot about that) where it stored all the data and it appeared as though everything was deleted from the ah

Changelog:

• added a shulker box sound when viewing a shulker box in the ah
• if you search for items, also shulker boxes that contain that item will be listed
• made an option in config.yml to put the currency symbol before the number (it's now possible to make it $4 instead of 4$)
• /ah sell <price> <amount>
• added a blacklist (/ah blacklist add <contains_lore|exact|material|name_contains>)
• made the item in the displays update not only when the material changes, but when anything of the displayed item is different
