Starship Battle update Ver. 0.7.1

Patch notes:
- removed scores (temporarily)
- fixed a bug relating to rotation speed

The reason why scores were removed was because their calculation was pretty dumb. This was found after playtesting showed that the winner would usually end up with a worse score than the loser.
In the future i would like to reintroduce scores mostly so one could measure themselves against their friends or foes.
