Resolved bug where player didn't have to perform capture if one was available. Known issues:

- Computer won't perform multiple captures (clicking on next capture position results in next capture being done, which means the only missing step is the trigger for the next capture location)
- If player moves to position where next move they will be able to capture, computer will not perform move (somehow is getting message that capture is required for computer, which means check is happening for player but verdict is being given to AI)
- If player piece is selected before it's officially player's position and then capture is performed, opponent checker being captured actually performs the move and then destroys itself (a cascade of errors follows)
