Use alternative way to modify game code

[mikroskeem]

1) Avoids legal trouble of having decompiled code in repository (I'm very sorry Omar!) 2) Cooler!

Few possible ways:

• Manual transforming using OW2 ASM (runtime)
• Mixin framework (runtime)
• Decompile & patch (like Paper is doing)

Don't have time nor care enough. PRs welcome if someone wants to work on this.
