Go-moku Apprentice 0.6

Go-moku Apprentice project consists of a gomoku player learning from its own mistakes.
Thus, for starters it plays like crap, but it gets real good after only a few games. Its rather scary actually.
Enhancements:
- With version 0.5, the apprentice playing engine has improved somewhat.
- Making a winning move always gets a score of INT_MAX, and making a losing move always gets a score of INT_MIN.
- The improved playing engine cost me some computing power, but Ive also been playing with gprof which should negate that effect somewhat.
