New Features :

- Controls : the serves are now separated from the strikes, so you can choose whatever combination you want, but without using the up/down that are reserved for the topspin/slice effects

Bug Fixes :

- Controls : pressing a strike combination that didn't use up/down while pressing up/down (eg: running to the net) wasn't activating your strike preparation and your player was still running
- Controls : it was not possible to put topspin nor slice in your serves
- Controls : the "Default" button for the keyboard controls was doing nothing
