[!] Fixed lava buckets being stacked when moved by hoppers into furnaces while having the hopper-move-amount set to 1 in spigot.yml
[+] Added support for MC 1.15
I didn't bother to add checks for hex color support, that means 1.15 users will see some garbled text where StackResize would normally use hex colors. Since this only happens in Admin commands, I figured it's not a big deal
