Joona tweaks of Weights and limits

Verification test give unusless result

After 999 games at 1+0
Mod vs Orig +250 =503 -246 50.20% +1 ELO

So we are well below our radar level. Neverthless
there are 100.000 games on Joona QUAD that we could
take in account and that shows that this tweak perhaps
has something good in it, altough very little.

Verification tests shows should not be a regression, at
least not a big one even in the worst case, so apply the
change anyway and keep the finger crossed ;-)
