Remove threat move stuff

Browse Source 
A great simplification that shows no regression
and it seems even a bit scalable.

Tested with fixed number of games:

Short TC
ELO: 0.60 +-2.1 (95%) LOS: 71.1%
Total: 39554 W: 7477 L: 7409 D: 24668

Long TC
ELO: 2.97 +-2.0 (95%) LOS: 99.8%
Total: 36424 W: 5894 L: 5583 D: 24947

bench: 8184352
