Leaderboard

After seeing how many players there were and how some of them were fighting for the best score, I really wanted to implement a leaderboard.

Well, it's 4 am right now, and I couldn't find sleep, so here it is, the leaderboard is implemented. 

The input for the name won't work on mobile yet, if it's requested a lot, I'll find a way to make it possible.

I also tried to fix a bug, where you would not be able to drop an item. Hasn't been tested much, so I hope it's fixed (fingers crossed)

Good luck trying to stand on top of the leaderboard!
