#skQuery function getSkin:
#First of all and to clarify things, why skQuery functions? Well, Skript functions don't allow delayed code when something is returned.
#That means it won't wait for the request to finish to return and as I'm using Reqn + Skript-JSON now, it'll not return anything.

#Parameters:
#Parameter 1 = the player who we will get the skin from.

#Examples:
#Can be seen below.
