Update 0.43 - Global Leaderboard

It's time to connect a bit more between ourselves, and earn your place on the board!

What's new:

• There's now a global leaderboard in the game! So you can see how everyone else is getting on. And get a bit competitive maybe. Let's see!
  
• Score is added automatically and current logged in username is used.
  

This is the first version of the board. Let me know any feedback or suggestions. It will most likely change over time as I figure things out!
