Version 1.1.2

Changes :
* Gameplay : Changed some spin parameters for serves : slices are more realistic, and topspin serves are more like kick serves, allowing "twisting" on slower speeds.
* Gameplay : Improved running with keyboard.
* Bug fix : Average stat in editor was wrong by an additional 2 points. Now displaying 2 decimal places.
* Bug fix : Circumvented Steam system to properly display online rankings.
* Bug fix : Sometimes hitting a button to end cinematic right at the end of set would also skip the stats screen.
* Bug fix : Copying a player in editor didn't allow the new one a different Unique ID. IDs that were duplicated that way will also be automatically fixed.
