Kotlin Port + New Requirements System

I have decided to port the plugin over to kotlin to keep up with my workflow. The only thing with this is the inflated jar size due to the kotlin library having to be included. All this means is a bigger jar size but this doesn't hurt performance at all. If anything this makes it easier for me to code out new features.

Changelog:

• Plugin rewritten in Kotlin
• New requirements system for rewards
• Moved wiki over to official site https://docs.illuzionzstudios.com/
