Define Score as an enum

Browse Source 
Increases performance because now we use one integer
for both midgame and endgame scores.

Unfortunatly the latest patches seem to have reduced a bit
the speed so at the end we are more or less at the same
performance level of the beginning. But this patch series
introduced also some code cleanup so it is the main reason
we commit anyway.

No functional change.
