Hydrinity optimizations & Lithium generation patches & more
Closes #257 

Ports 2 patches from Purpur: Infinity-bow-settings & Allow-infinite-and-mending-enchantments-together
Added an option for infinity with no arrows too.

Option for custom locale has come! You can put a locale.json file in your server folder to change it. 

We've got the finest patches from Hydrinity ( Mykyta approved & allowed ) too.

We have some amazing new options in yatopia.yml, we're gonna have documentation for them soon so stay tuned!
Last but not least, chunk generation patches. We've tested them extensively so no weirdness happens.

Thanks for using Yatopia as your production server software.
