* Changed PlayerQuitEvent priority to HIGHEST to prevent NullPointerException
* fixed a bug that #isNicked didn't work properly
Added 2 new API methods:
Code (Text):
boolean isNickSet( Player player );
boolean isSkinSet( Player player );
isNicked only works if player is refreshed completely. This means isNicked does not work in real time. Use isNickSet and isSkinSet instead.
