Simplify skill level and reduce ELO This patch has two positive effects: - Retire a hackish formula and leave just a natural, simple and plain one. - Reduce strenght at very low level, but don't impact medium/high levels. Actually even at level 0, SF is still too strong for many beginners (this was reported many times for instance on Droidfish user comments on Google Play). Test on fishtest shows that ELO drop is around 170 ELO at level 0 (good!), 130 ELO at level 1 and smoothly reduces (as expected) until level 10 where the drop is just of 8 ELO. No functional change.
