[5.0.2] Much smaller file, some improvements and bugfixes
Important: Save your configuration somewhere before you update to be able to restore your changes!
The jar-file is now much smaller (59kb).
Also fixed a bug and removed some annotations.
Just noticed that there is a bug in the api(may concern older versions, too): isInvisible() always returns false. Use getInvisiblePlayers().contains(p.getUniqueId().toString()) instead
