Updated the way we load and save the config. This issue was causing quite some issues for some users, hence the update.

Any feature requests are welcome!

• Recipe advancements can now be configured to count towards growing the worldborder.
• Separated the growth-parameters per growth reason. So recipe advancements and regular advancements can have separate min and max growths.
• Overall improvements to the way the worldborder growth is calculated.

Sorry for the delay in updates!

Fixed a bug where the worldborder wouldn't expand if recipe advancements were set to true.

The worldborder should now properly expand.
