Endstone Tebex Integration

• An extensive config where you can change pretty much every part of the plugin, even text you'd see in the front end for translations (and you can use formatting codes to change colours), and behavior of subcommands.

• QR codes. With /tebex store, players get both a plain text link to the webstore, and a QR code map that can lead them to the web store. This is optional--you can disable it in the config.
