Capture 3 stones has an additional rule: A player may not play a stone so that it creates a past board position. So repetition of full-board position is not allowed.
Implemented simple (and limited) tournament mode. This mode disables AI tools, so they cannot be used accidentally. Mode can be set in settings. Better interface for the mode will be created later.

After the game ends, a result is calculated. Any stones that opponent could capture are calculated as captured. Players points are the sum of following: * The territory he has surrounded, * Captured and capturable opponents' stones. White usually gets some extra compensation for blacks' right to start the game. This is called komi. Hactar uses Japanese rules for calculating result.
