The large majority of Red Warfare's code
To get this running you will need a MySQL server and a redis server. You will need to change the settings in MysqlManager and RedisManager, its not user friendly as it was hardcoded. It was hardcoded namely because I didn't believe it would ever be released to the public, and if the plugin was leaked then I'll need to change the login details regardless.
For the build server, it should require some work to get running.
You may notice that some references to outside projects are missing, namely a server spinner and manager. Those managed the servers themselves.
In the process of updating to 1.12.2 some features may have been broken.
