Drawasaurusuh troch Obtuse Goose Ltd

Makes several improvements to the user interface at drawasaurus.org:
• Adds numbers after the clue e.g.: instead of
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
you see
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ (11,6)
• If you type and the guess box isn't in focus, it automatically switches to it.
• If the "Still playing?" 15 second timer pops-up, it automatically clicks it for you.
• Disables the back button so you don't get kicked-out of the game if you accidentally click the back button on your mouse whilst drawing.
