THE API HAS BEEN CHANGED! IF YOU ARE USING THIS UPDATE, YOU NEED TO UPDATE YOUR OWN PLUGIN!

+ Added #isNicked method ( Thanks to @xXPixelCookieXx )
+ Added a parameter to the method #nick which allows you to change your skin or not

Thanks to @NurPech

skinChange : boolean - allows you to nick into a player without "leaving" your own skin - Example: /nick GommeHD - I will keep my skin but will have the nametag of GommeHD

* Fixed a bug on the methods #getNewSignatures & #getNewValues
