added win conditions to check_winner in game.py 

What I changed
I added the 8 possible tic-tac-toe win conditions to check_winner and
compare the values in the state with the symbol passed to the method

Why I changed it
It took a WHILE to figure out how to actually read the current state of
the game, but once I had that, I was able to figure out how to check
it for the symbol being sought.

Estimate for remaining time to finish assignment: [1 hour?]
I thought it was "how long did it take" now "how long remaining" originally.
