Work on guessing game

I finished all the code for the actual guessing game, which works beautifully now, and then spent about 45 minutes completely failing to get a highscore table to work. I may try again next week, but at home I'll work on getting it to use the datastore and not just the memcache.

I had written the code for the game, but eventually had to move it to make it more sensible and work better - moving much of the logic from the post to the get function. I have not yet uploaded it to Google's servers
