Winter Championship

The version of Shapeshifter that is playing the winter championship 2022

Correct move generation

Two critical bugs in move generation were fixed.
Previously one of these would lead to the creation of infinite loops in the search thread which eat up more and more CPU cycles the longer the server runs.

Area Control

Add area control with rudimentary weights to eval funtion.

Bitboards

Only works on 11x11 boards at this point.
