Mastercraft is a simple application that aims to replace the master server, allowing authentification of users registered
to the server.

It requires clients & servers to redirect to the master server
IP address (by using /etc/hosts for instance)

This was made because :
 - The master server is down quite often, and it's very frustrating
 - Disabling online mode on the server is too dangerous

It's a better alternative to server mods that require to type a command to login
such as /register <password>
