Probability Adjustment tweak
Fixed it so that if there is a space where the end of a ship cannot exist,
it recognizes the possibility that the center of the ship could be there.
The AI*_*1s are the ones with this new implementation. In 100,000 runs,
there were only fractions of a percent difference between the two versions
so it obviously wasn't having a very serious impact on the games.
Also, minor changes and added functions for the TestPanel.
