Changelog:

- added compatibility with EssentialsX (if you still have issues, feel free to contact me on my new discord server - https://discord.gg/ePTwfDK6AY)
- made item displays immune to /teleport
- item displays are now removed when the glass dies with /kill
- added formatted numbers (1,000,000 instead of 1000000)
- added the option to change the filler item and to modify the amount of max auctions
- support for more than 21 max auctions per player (multiple pages appear then)
- added a message when a player buys your auction and a click interaction to instantly collect the money

To do:
- Make all the messages customizable. That way the plugin can be translated in other languages. This will likely be the next big update (I'll have to convert all those hard coded messages in the code to linked ones, help), unless there's a critical bug in this version.
