Subject: Tweak default values for ucioptions

Tweak default values for ucioptions

I created three different systems, tested them all separately and
attached one did best:

1/40: Orig - Mod: 841 - 850 (+2 elo)
1+1 : Orig - Mod: 474 - 498 (+9 elo)
1+0 : Orig - Mod: 455 - 495 (+15 elo)

Because such testing system is not statistically reliable, I made a
confirmation test:

1/40: Orig - Mod: 502 - 543 (+14 elo)
1+1: Orig - Mod: 447 - 489 (+16 elo)
1+0: Orig - Mod: 641 - 656 (+4 elo)

All tests show positive score :-)
