BetterLife 1.0! - Complete Refactor

• This release didn't bring much in the way of new features, but it does bring a complete refactor of the code base to be much easier to work with and much faster!
• It removed a lot of the bad practices and stupid stuff (such as making a new instance of a command class upon every single usage of the command).
• Plus now we have Gradle, and the jar size went from a stunning 4.5MB to just around 810KB! Now those are some cute savings!
• The plugin also now supports only 1.17+ and Java 16 is required.
