[Freeciv-Dev] (PR#4756) Spaceship doesn't give win regarding to ranking on pubserver

["Guest" <rt-guest@xxxxxxxxxxxxxx>]

Hello, 

Yesterday, in a "peaceful" online game (175888), my spaceship reached
Alpha Centauri. While that another player conquered most of the world.
At the end of the game the scores were :

- warlord : 851
- space traveller : 691

As the "real win" went to the other player in the ranking system, I
think there is a problem because winning with spacerace isn't point-related.

I have no good idea on how to solve that except a "score-cooking" like : 

fA = (A + B) / 2 
fB = ((A + B) / 2 ) + 1

with :
A = greater score before cooking
B = space traveller score before cooking
fA = non-space traveller score after cooking 
fB = space traveller score after cooking

fA and fB are the scores took into account for ranking.
