Explode the weird gamecore.h/gamecore.cc containing too many classes.
- Player => player.cc/player.h
- AttackFleet, DefenseFleet, Fleet => fleet.cc/fleet.h
- Planet => planet.cc/planet.h
Left in gamecore : CoreLogic and Map/Sector classes.


Also introduce a bug in the scoreTable, but this kind of thing is better left unsaid I suppose :)
