WIP Rust

A Ragnarok online server implementation from scratch.
Ragnarok online was an MMORPG I played a lot between 2006 - 2010, when I wanted to learn rust, I was looking for a project I would not lose interest in after few months. Thanks to the nostalgia provided by this game, I was able to work on this project for years, and improve my knowledge with rust.
