Highscore system for minigames

[fvultier]

It would be nice to have a highscore list for the minigames (and probably certain other levels).

Important design steps/decisions:

• Where should the highscore list be saved? Probably on the master server?
• Somehow the game should be able to read the current highscore for a particular level from the masterserver. How can you implement this?
• After terminating a level (and having a higher score than any other player) you should be able to send your score to the masterserver.
• There should be a way how the player can enter his/her name when having a new highscore. Create a GUI where the player can enter the name.
