+ Added support for Spigot 1.17 R1
+ Redid the entire sell command system
+ You can use command flags (currently only -b) in the sell command. (Ex. /ah sell -b 500) Using -b will bundle all similar items found in your inventory based off the current one you're holding and sell it as one.
+ Updated to latest TweetyCore
+ Fixed* bug with sale type filter
+ Attempted fix regarding the concurrent modification error that's been seen in the console.
+ Added two new translatable strings regarding commands. The first being the no permission message, and the second being the invalid syntax message.
+ Added two extra command aliases for auction house (ahgui and auctiongui)

- This is an example of the bundle system.
- Bundled items can be claimed by right clicking the item while holding, they cannot be stacked, each bundle has a unique id.
- You can inspect bundles like shulkers (shift-right click inside the auction gui by default)
