MonkeyBot final patch, I hope
Cleaned up some unused code.
If bot can not find a winning row, or a row to block, it will now randomize next move with a priority of center position, then random corner, and finally if center and corners are taken already, random of the "boring positions"
Bugs: sometimes you have to say No two times if you don't want to play again, bot really likes playing with you!
Feature: Human touch, sometimes bot forgets to block
