Leaderboard added!

Hi guys!
I added a leaderboard to the game :)

I used a solution provided by Carmine Guida (http://dreamlo.com/), which is available for free on Asset Store

Fun fact: This guy is a legend! He started the whole thing in 2012 and is still taking care of it! I sent him a donation with great pleasure for all his commitment.
