Changing pieces from # and * to O and X
Adjust board numbering; add resign and co
Adjust board numbering, add announce_move and resign methods (for AI)
Using sys.maxsize; fixing streak counting; enhancing evaluation

Using sys.maxsize to represent infinity, rather than 99999999

Accounting for smaller streaks in value

Breaking lines > 80 chars
Compacting methods better.
Major clean up, now actually returning highest value move
No longer re-printing board after end game.
Finalized evaluation heuristic. Auto now results in draw.
